Biochemistry in the aquarium: Large-scale calcium and alkalinity maintenance. Pomeroy and J.J. Alberts (eds. By manipulating the acidity of the Biosphere 2 ocean and measuring the resulting growth rates in coral between 1996 and 2003, Langdon proved that ocean acidification from rising atmospheric carbon dioxide would radically affect calcium carbonate–shelled marine life (pdf). RNN Episode 149 – Admin Takeover: Deep Dive Dosing, We put 30 Ecotech Radions over this Reef Tank. 2. Science 329: 322–325. In addition, as mentioned previously, increased nutrient levels can have other impacts other than on growth such as on reproduction and the ability to withstand bleaching (D’Angelo and Wiedenmann, 2014). They will survive under less, but your growth rates will slow drastically under medium-low lights. This image illustrates how scientist measure a coral for size and growth rate. Nutrition of corals is also gaining added importance as simply providing enough light is not adequate to keep corals in a high state of fitness. Brittsan (2004) reported a range of 0.01 to 1.3 mg/L phosphate amongst 16 public aquaria surveyed with a mean of 0.28 mg/L. Some of this conflicting work can be explained by the level of nutrients used, the duration the nutrients were maintained at a high level and the nature of the nutrients present or used. Achterberg. Ross, R. and C. Jury. There can even be variation within a species for example Acropora longicyathus showed no increase in growth at 0.22 mg/L PO4 whereas at levels of 0.48 mg/L it did while in another study the opposite occurred where levels of 0.204 mg/L had no effect on calcification in Acropora cervicornis but at 0.393 mg/L it decreased (in Dunn et al., 2012). and T.C. A good test is to measure dKH and then a week later and without dosing, measure dKH again. Jokiel, P.L., and S.L. Perhaps the fasting growing of the soft corals, Xenia, comes in a few varieties with the most popular being the pulsing kind. Determining starting Rowaphos dosage when testing 0, Clarisea Mod For Apex Control With Optical Sensor. Delbeek, J.C. and J. In this piece I propose that having a fast growth rate is not necessarily an indication that a coral is healthy and doing well (see also Woodridge, 2014) I’ll also take a look at the recent reports of higher nutrient aquariums doing well (see Ross and Jury, 2014) and offer some suggestions as to what might be going on with these; though I am the first to admit this is only educated speculation. ), Concepts of Ecosystem Ecology. The algae scrubber was invented by Dr. Walter Adey, who beginning in the late 1970s, was Director of the Marine Systems Laboratory at the Museum of Natural History, Smithsonian Institution (Washington DC, USA). With this increased input of nutrients comes an equal increase in nutrients such as nitrogen and phosphorus, which must be dealt with either via the life support system (LSS), by system maintenance routines or by a combination of both. R. Soc. Koweek wondered if it might be possible to spur coral growth by reducing CO2 levels in the water in the predawn hours – when the oceans are most acidic – by using air bubbles to draw the gas out of the seawater and transfer it to the atmosphere. 4. While these are certainly acceptable ranges, there are also instances where higher levels of nitrate have occurred in closed coral systems with no apparent negative effects, which we shall examine shortly. Calcification rate and the effect of temperature in a zooxanthellate and an azooxanthellate scleractinian reef coral. (The ruler in the pics is 12"). While high levels of nutrients are often cited as reasons for reef decline, there is a lot of conflicting research on the subject. Calcifying organisms such as corals tend to calcify best at a pH of 8.2-8.5 due to a variety of factors such as calcium and alkalinity availability, and carbon dioxide levels. Ecol. If you’re using Kelvins try to get 10,000k or above. Together these make possible the conditions needed for corals to be able to calcify which is the process whereby inorganic carbon and calcium are combined inside the coral to create the calcium carbonate skeleton upon which a coral’s tissue resides. 2008. tide pools. don't put you finger near that mouth ! Protein Skimmers Consumption and Growth Rate (2016-2021) & (K Units) Figure 39. However, Wooldridge (2014) recently postulated that recent evidence such as that mentioned in this article links fast skeletal extension rates with elevated coral-algae (symbiotic) respiration rates, most-often mediated by nutrient-enlarged symbiont populations and/or rising sea temperatures (Wooldridge, 2014). The Hammerhead coral is no exception. Low temperature FESEM of the calcifying interface of a scleractinian coral. System level studies. The fact that we are able to grow corals under a variety of nutrient regimes is more a reflection of the adaptability of coral and the complexity of their relationship with both symbiotic algae and the bacterial fauna associated with corals, the so-called holobiont. Sprung. The Reef Aquarium: A Comprehensive Guide to the Identification and Care of Tropical Marine Invertebrates. It is better to maintain natural levels of calcium whenever possible. The Blue St. Thomas Mushroom is a beautiful species covered with big bubbles which almost make them look like Blue bubble tip anemones. Marine Biology 43: 201–208. These higher than normal levels provide sufficient carbonate and bicarbonate to balance the negative effects of elevated nitrogen and lowered pH and allow for enhanced calcification rates (Marubini and Thake, 1999; Comeau et al., 2012). I had always maintained keeping it somewhere below 27 oC (80 oF) while others argued that it should mimic natural reefs and could run as high as 32 oC (87 oF) (Shimek, 1997). These are: temperature, salinity, calcium, alkalinity, and pH. Voss, J. D., and L. L. Richardson. Some grow very large some stay smaller . Karnauskas, A.M. Tarrant, and D.C. McCorkle. All you have to do is put their food on one of the polyps located along the coral, then your coral friend will trap the food in its tentacles or vesicles and gobble it right up. Reverse Superman monti vs tabling acro. If algae growth occurs, stop dosing. Adey, W.H. D’Angelo, C. and J. Wiedenmann. Also, be sure to give it adequate room for its sweeper tentacles, as they will sting neighboring corals. Calcium – 450-465ppm. However, there is no denying that successful coral exhibits can be found that have considerably higher levels of phosphate i.e. To further the potential for confusion most aquarium labs report in units of mg/L while most scientific publications report these values in micromolar (μM)units, therefore it is critical to know not only what form is being reported but how to convert between the two units of measurement. Ocean warming slows coral growth in the Central Red Sea. Chronic nutrient enrichment increases prevalence and severity of coral disease and bleaching. The rate that this occurs depends on the species. They live in cozy bubble coral home.Bubble coral opens when in light and closes when in the dark and is in Indonesia .They use their hairs to camouflage when not in their home. In general, all LPS corals have developed several different ways of getting their necessary nutrients. lipids) needed to sustain essential homeostatic functions, including sexual reproduction and biophysical stress resistance is restricted (Wooldridge, 2014). Quest Rewards ※ You can acquire [Coral Jelly] upon completing a [Growth… Vol. Fabricius, K. E. 2005. Progr. But questions have now arisen if maintaining low levels of nutrients is really critical and discussion of systems which much higher levels of phosphorous and nitrogen are taking place (see Ross and Jury, 2014). Coral growth rates can depend either on species, on their structure or on the combination of both.. 2004. U.K. Organism responses to rapid change: What aquaria tell us about nature. It is possible that closed system coral tanks could have even higher calcification rates when alkalinity is boosted and the surface area is dominated by fast growing corals such as Acropora as well as coralline algae, and calcification rates of 20 kg (44 lbs) of CaCO3 /m2/year could be expected (Bingman, 1997). Typically seawater alkalinity can vary between 2.1 and 2.5 meq/L depending on location, with a value of 2.3 meq/L considered average. I. For example the progression of diseases such a black and yellow band disease can increase when nitrate levels are elevated (Voss and Richardson, 2006). One of the controversies that I weighed in on almost 15 years ago was the correct temperature at which to keep a reef tank. Crystal clear waters on a reef in the Solomon Islands. You should see some noticeable coral growth every week. Coles. However, I believe these challenges in variables also provide an exciting opportunity for further investigation, and with the rapidity with which our climate and our consequently our oceans are changing, the insights provided by our tiny slices of reef may provide a window into our future and may yield surprising findings. Ecol. Marubini, F. and B. Thake. Ser, 188:117–121. 1988. Moreover, this may explain the somewhat paradoxical scenario, whereby at the ecological instant before the reef-building capacity of the symbiosis is lost, a reef can look visually at its best and be accreting CaCO3 at its maximum (Wooldridge, 2014). Utilization of dissolved inorganic nutrients in growth and mariculture of the tridacnid clam Tridacna derasa. Values as low as 360 mg/L can be fine too just so long as alkalinity levels remain in balance, or even higher, with calcium levels. The Microcosm: A new tool for reef research. Macronutrients N P K levels and management. Estimations for closed systems have ranged from 0.5 to 6.5 kg (1.1 to 14.3 lbs) of CaCO 3 /m 2 /year (Carlson, 1999). Due to the actions of biological filtration, feedings and heterotrophic bacteria, nutrient levels in closed systems often exceed those of in situ coral reefs by a factor of 100 or more. The bubble coral is not to be mistaken for a soft coral or fish eggs, bubble corals are stony corals with skeletons just below their fleshy surface. 2013. Order: Corallimorpharia ( Mushroom coral ) Family: Actinodiscidae Actinodiscus ( disk anemones - false coral ) Corallimorphs also known as the Mushroom corals are easy to keep in captivity. Nutrient enrichment can increase the severity of coral diseases. Bubble Corals are found throughout the Indo-Pacific and can be recognized by their smoothy pearly vesicles. This coral should be placed low in your aquarium, either on the substrate or a low-lying rock. Coles. High coral cover on a fringing reef of Guam indicates high demand for calcium carbonate. 1977. #UOR #orangutan #seacrab #ocean #indonesia @Uorrescue #uorstory #uor #marinemammalrescuelg #oceanacidificationawareness Uorrescue.org • •Videocred @atsushisadaki . Response of Hawaiian and other Indo-Pacific reef corals to elevated temperature. In this episode I talk about my experience keeping a green bubble coral. When one thinks of coral reefs, images of gin clear, nutrient poor blue water spring to mind. If you only want growth, you can choose a 6700k light for extreme efficiency, however the light will be fairly yellow. Your email address will not be published. Bubble coral eats shrimp or small bits of clam, and you should feed them one or two times per week. There are a variety of water quality factors that are important to maintain in systems that are designed to house live corals. The pH of seawater can vary depending on locale, but can range from 8.0 to 8.5. You are using an out of date browser. Marine Biology 139:1057-1068. It seems healthy but is Much larger than I expected. Water Parameters. As previously mentioned, nitrate can act as a source of nitrogen for zooxanthellae, enhancing their numbers causing the coral to darken in color. B 2013 280. Nature Climate Change 3:160–164. Regular phosphate tests are only capable to measure PO4. 2010. Proceedings of the 11th International Coral Reef Symposium, Ft. Lauderdale, Florida, 7-11 July 2008. www1 – http://www.endmemo.com/chem/molarity.php. Keep all of your water parameters within the recommended ranges (see below) along with the proper lighting and you will be pleased with your monti's growth rate. Wiedenmann, J., D’Angelo, C., Smith, E.G., Hunt, A.N., Legiret, F-E., Postle, A.D. and E.P. Acroporid corals have lower fecundity, egg size, fertilization rates, and embryo development at even very low levels of nitrogen concentration of 1 μM NH4 (0.02 mg/L) (Fabricius 2005). Hammer Coral Feeding & Growth As with any other coral, it’s necessary to understand their feeding requirements if you want to have success keeping them. Joined Apr 7, 2018 Messages 25 Reaction score 11. 1999. Bubble magus roller filter small - float valve height. ※ [Bubble Coral] can be purchased at the Crystal Point Shop for 6000 Crystal Points. In live coral systems, a slightly elevated level of ammonia in source water is acceptable as the zooxanthellae algae in the corals will readily uptake this as a source of nitrogen. Coral reefs grow best in warm water (70–85° F or 21–29° C). Did I make a nutrient or chemistry mistake? Xenia . Conversely, in systems with elevated nutrient levels and low coral cover, they will be under much greater strain to compete for nutrients if algae have gained a foothold. Feeding. Ecology Letters 6:1056-1061. Aquality Symposium 2004. https://sites.google.com/site/aqualitysymposium/manual. Nutrient enrichment enhances black band disease progression in corals. Our curiosity hasn’t ended there. Estimations for closed systems have ranged from 0.5 to 6.5 kg (1.1 to 14.3 lbs) of CaCO3 /m2/year (Carlson, 1999). Borneman, E.H. 2008. This coral requires a water temperature of 74-83°F (23-28°C). I feed mine a piece of shrimp last week and seems to be hungry every night ever since. 2012. and S.L. About 2 years ago I set up a basic reef tank and one of the first specimens was a bubble coral. Coral Reefs 1:194-201. 411:34–44. There are so many factors in our aquaria that are not analogous to natural reefs that really, we are dealing with an entirely different beast so trying to draw conclusions about what is going on with these elevated nutrient systems is challenging and may actually be fruitless. Bruno, J. F., L. E. Petes, C. Drew Harvell, and A. Hettinger. Marubini, F. and M. Atkinson. Carlson, B.A. Generally it is recommended to keep phosphate levels as low as possible with levels somewhere between 0.03 and 0.08 mg/L considered ideal (Brittsan, 2004; Borneman, 2008; Delbeek and Sprung, 2005). Fighting SPS. Therefore it is tempting to speculate that having both elevated P and N in an aquarium might be okay, but having only elevated N but lower P is not. Langdon, C. and M. J. Atkinson. The biggest in my mind is the staggering discrepancy in scale, in other words the much higher density of calcifying critters in proportion to the volume of water. However, there are five that are essential and if they are not maintained at adequate levels, then coral will not be able to thrive. Proc. Placement. Large Polyp Stony Corals (LPS) are the builders of calcium carbonate reef structures found in the wild. 1994. Typical Size. ), pp3-14, Advances in Coral Husbandry in Public Aquariums. Such levels can be obtained in closed systems (Delbeek, unpublished data) but usually levels range from less than 1.0 to 40 mg/L or even higher. Marshall, A. T. and P. Clode. and G. LaFleur Jr. 2012. Inshore reefs, not surprisingly, can experience significant shifts in nutrient levels, salinity and temperature, and are more susceptible to anthropogenic influences such as silt and sediment run-off, and the resulting nutrient spikes this can bring. and Ecol. By Elizabeth Larcom, Graduate Student and Charles Fisher, Principal Investigator - Pennsylvania State University. Limnol. 1: Stony Corals and Tridacna Clams. Comeau, S., Carpenter, R.C. In closed system it seems to be fairly well-established through experience (Delbeek and Sprung, 2005; Pawlowsky, 2008) and experimental evidence (Marubini and Thake, 1999) that maintaining elevated levels of alkalinity can overcome limitations on coral growth caused by elevated levels of nitrogen and phosphorous. Certainly the role of nutrients in coral health is much more complicated than previously imagined as evidenced by the many studies that appear to provide conflicting results. Corals will also darken in color as the number of zooxanthellae increase as well as an increase in pigment density. Higher than 10,000k makes the corals look nice, but 10,000k will give you the best strength per watt. NO3-N, nitrate-nitrogen; NH4-N ammonia-nitrogen). 2014. The color isn’t very common with coral or invertebrates. 45. When they’re first sold, Bubble Tip Anemones usually measure a few inches in diameter. ※ You can complete a quest upon speaking with the quest NPC while in possession of 1 [Bubble Coral… Due to growth pattern and growth rate, I have my doubts if it’s scientifically an Acropora tortuosa at all. Ser. The real question is whether or not corals can change their thermal maximums over time as they adapt to a new environment. 2003. Using scanning electron microscopy Risk and Sammarco (1991) demonstrated that the lower skeletal density that results from increased nutrients such as phosphate was due to increased porosity and a decreased in thickness in the structures of the coral polyp calice itself. Branching and staghorn corals can grow much faster, adding as much as 20 centimeters (8 inches) to their branches each year. For example, natural seawater levels of ammonia in in-shore water off of the Waikiki Aquarium in Honolulu, run around 0.001 mg/L yet the saltwater well that supplies water to the live coral exhibits has a level of approximately 0.05 mg/L and the corals do just fine. Yuen et al., 2008), however, as has already been mentioned, this effect can be offset by maintaining alkalinity above 3.0 meq/L. "The nice thing about the bubble pulse method is that it provides an engineering technique that can help bring us closer to conditions that coral reefs were used to 100 years ago, and to which they've been adapted for many thousands of years," said study coauthor Rob Dunbar, the W.M. Oceanogr. J. Exp. Effects of lowered pH and elevated nitrate on coral calcification. It may not display this or other websites correctly. 1983. pH – 8.0-8.3. dKH – 12.0-12.5. Introduction to the husbandry of corals in aquariums: A review. **AQUA SD SPRING LIVE SALE** 2/27 & 2/28 SAT & SUN - 3,000+ CORALS - 2 Days - PRIZES. Magnesium – 1370-1390ppm. Coral Growth Rates and Sizes. While it is true that some very high diversity reefs can occur in areas where water temperatures can run up to 32 °C (87 °F) for extended periods, such temperatures are approaching the thermal maximum for most corals; especially those that do not come from habitats that normally experience extended periods of high temperature e.g. If the bubbles have lower concentrations of CO2 than the surrounding water, the gas will naturally diffuse into the bubbles. bubble coral growth. In general, coral growth (annual linear extension) rates in the tropics are found to be negatively correlated with annual mean SST, and this relationship is often used to reconstruct past sea surface temperature (Cantin et al., 2010). Once you’ve filled out some empty space in your aquarium with fast growing mushrooms, large leather corals, xenia, and bright green star polyps, you can add a splash of color with some fancy Zoanthids. didn't know that . Some varieties of LPS such as Favites can grow very quickly while some massive LPS like Trachyphyllia can take years to grow an inch. Photo B. Carlson. Global Change Biology 20(2):544–554. What is not clear is what are the upper limits that these two nutrients can reach in closed systems and still be tolerated by corals due to high alkalinity levels. There is also evidence to suggest that when nitrate is elevated and phosphate is not, that corals are more susceptible to bleaching that is both light and temperature mediated, but if both are elevated, the zooxanthellae increase in numbers and the coral becomes darker and is not as susceptible to bleaching (D’Angelo and Wiedenmann, 2014; Wiedenmann, et al., 2013). The performance of both light sources was evaluated by measuring the specific growth rate of each coral species, as well as by subjective photographic analysis of their morphology and colour for a six–month period. In a survey of 16 coral systems at public aquaria Brittsan (2004) found that NO3-N levels ranged from a low of 0.13 mg/L to a high of 10 mg/L, this equates to 0.57 mg/L and 44 mg/L of NO3 with a mean of 12.2 mg/L NO3. One of the common fallacies still perpetuated by some is that coral reefs are these remarkably stable environments that experience an almost steady-state existence. This is due to the fact that not only do they come in an Metabolism, calcification, and carbon production. Today, with reports of coral bleaching occurring more frequently, it is not surprising that temperatures just a few degrees above the annual average can result in coral bleaching and greater susceptibility to diseases. Harrison, P., and S. Ward. I have a small pearl bubble.... what and how freq are you feeding?? Several studies on nutrient enrichment of ammonia at much higher levels than at Waikiki (e.g. As with nitrogen, inorganic phosphorous levels can be reported either as phosphate-phosphorous (PO4-P) or phosphate (PO4, also known as orthophosphate) and results can be reported as either μM or mg/L, therefore as with nitrogen it is critical to know which format test results are reporting and in what units before you start comparing numbers. Diametric and linear growth rates of red coral (P. Japonicum) were slower than pink (C. elatius) and white (C. konojoi) corals. A collection of various aquarium testing kits and tools. Elevated levels of nitrogen and phosphorus reduce fertilization success of gametes from scleractinian reef corals. Diametric growth rate of the Japanese red coral (P. japonicum) is slower than the Mediterranean red coral (C. rubrum). Therefore it is vital that these factors be considered together and not as individual components of water quality for a live coral aquarium. It can tolerate a fair range of levels but you should always aim to keep things as close to perfect as possible. Tissue Cell 34:187–198. It should also be pointed out that high coral growth rates alone are not an indication of coral health as it should be obvious that this increased growth rate is artificially enhanced through excess nutrients, resulting in a less dense and hence weaker coral skeleton. However, experiments to determine the effects of increased phosphate levels on coral growth are mixed, with some species showing increased growth, some showing a decrease while others exhibited no difference. The growth rates of hard corals are species dependent, with certain species growing much quicker than others. It is critical to know for reporting and comparison purposes, which of these two values are being reported. Add it at a minimum of every second or third day. However, experiments have indicated a parabolic relationship between coral growth (calcification and/or linear extension) and SST (Jokiel and Coles 1977; Jokiel and Coles, 1990), with highest growth rates found at temperatures 1 to 2 °C below the mean annual maximum but if the temperature increases just a few degrees (1-2 oC) above the peak seasonal high a drop in calcification rate results (Marshall and Clode, 2004). They are hardy and easy to care for and come in … Public Aquarium Husbandry Series vol. Since the site was first deployed, we’ve been measuring the growth rates of 30 unique coral genomes across the Artificial Atoll and comparing those against their counterparts on our control dome that was placed at the same depth approximately 50 meters away. The trade-off is that these skeletons are most likely less dense than wild colonies (see Carlson, 1999). Strontium – 8.5-10ppm. Since Xenia is such a quick growing coral it is also really cheap and you can often pick up big rocks or healthy sized colonies at your local fish store. However, the price for coral growth in higher nutrient water is that the skeleton produced is less dense and hence more brittle, which has been observed in both corals and giant clams that were grown under higher levels of ammonia and nitrate (Fitt et al., 1993; Carlson, 1999; Marubini and Flake, 1999). France Protein Skimmers Consumption and Growth Rate (2016-2021) & (K Units) Figure 38. The real question is why? and K. Loveland. Academic Press, Inc., 643 pp. About 2 years ago I set up a basic reef tank and one of the first specimens was a bubble coral. American Zoologist 39: 44-55. Nitrate (NO3) levels around coral reefs can vary depending on location and season but generally they are rarely above 0.05 mg/L (D’Elia, 1988 in Delbeek and Sprung, 1994). ※ [Bubble Coral] can be purchased at the Mission Bulletin Board Shop for 30,000 Hero's Blood, Sweat, and Tears. In closed systems, a range of 2.5-3.5 meq/L is generally recommended with a target of 3.0 to 3.2 meq/L considered ideal. When combined with photosynthesis from the zooxanthellae algae in the coral tissue this drives the process to the right by taking up carbon dioxide. Heterogeneous dissolved organic nitrogen supply over a coral reef: first evidence from nitrogen stable isotope ratios. For a better experience, please enable JavaScript in your browser before proceeding. Long-term effects of inorganic nitrogen enrichment on the reef-building corals Stylophora pistillata and Acropora spp. so there are different verities? 6:505-526. 40 μM vs. 3 μM), have shown a decrease in coral growth rate (e.g. JavaScript is disabled. The pH level of a coral aquarium is just one part of a complex system that also includes calcium, carbonate alkalinity and magnesium. However, they can quickly grow to about a foot wide! Photo by Brian Cook. The increase in algal cells also increases competition for inorganic carbon which can result in decreased coral skeleton growth though this can be offset by increasing the level of carbonate alkalinity (Marubini and Atkinson, 1999; Marubini and Thake, 1999). Nitrate has a number of effects on corals. Aside from these direct effects indirect effects can include increased algal growth in the system that can outcompete the corals for growing space as well as nutrients.

Impacts of nutrient enrichment on coral reefs: new perspectives and implications for coastal management and reef survival. Overfeeding is unhealthy for both your coral and the other fish in your tank, so don’t do it. Brittsan, M. 2004. The Reef Aquarium: A Comprehensive Guide to the Identification and Care of Tropical Marine Invertebrates. Therefore the reports of success under much higher than generally accepted nutrients (Ross and Jury, 2014) can be partially explained by the fact that the alkalinity levels in these systems is higher than natural seawater. BioEssays 36(11):1041–1049. Factors that Affect Coral Growth (Linear Extension). Corals rely on water chemistry and light in order to build their calcium carbonate skeletons, a process known as calcification. Thibodeau, B., Miyajima, T., Tayasu, I., Wyatt, A.S.J., Watanabe, A., Morimoto, N., Yoshimizu, C. and T. Nagata 2013. See pages 133-139 in Delbeek and Sprung (2005) for a more in-depth discussion of the ideal temperature for a closed reef aquarium system. Montipora Digitata go by a couple different common names such as the Velvet Finger or Velvet Branch Coral … Effects of temperature on the mortality and growth of Hawaiian reef corals. This is a definite advantage and allows these corals to quickly colonize new areas. 44(3):716–720. Let’s start with a 10 hour photoperiod; are your corals growing? In: R.J. Lewis and M. Janse (eds. 1999. Want to grow your business and reach a wider audience? His research of various types of algae, especially in their ecological role on coral reefs, gave him insight into how the ocean (in particular a reef) "recycles" nutrients. Yuen, Y.S., Nakamura, T., Yamazaki, S.S. and H. Yamasaki. Coral Reefs 25:569-576. Dunn, J.G., Sammarco, P.W. To increase the growth rate of juvenile SPS/LPS corals, coral frags, and clams, Orphek recommends that you maintain the following water parameter levels: Salinity – 35ppt (1.026) Note: Orphek recommends and uses Seachem’s Aquavitro salt. The levels of each can be measured and reported in two forms, the nitrogen ion and the nitrogen containing compound. Vol.3: Science, Art and Technology. The general recommendation is to keep nitrate below 1.0 mg/L with a range of 0 – 10 mg/L considered acceptable (Borneman, 2008). Marine Pollution Bulletin 50:125-146. Public Aquarium Husbandry Series vol. The days of corals merely growing being a sign of success are gone as a renewed interest in spawning and propagating corals has resulted in a renewed emphasis on providing feeds to corals.
