![]() What would happen if there were no algae in the marine tank.And today’s article will walk you through the marine algae in coral reefs and marine tanks. The marine algae we will discuss are those that grow in saltwater aquariums, like coral reef tanks. Being classified into beneficial and harmful algae, marine algae usually refer to those that grow in the sea or ocean, or on rocks at the edge of the sea or ocean. I feel that it’s whatever extra elements that may be in higher concentration than necessary basically precipitated out.Aside from the algae in freshwater aquariums, there are also marine algae in coral reef tanks. The only downside I’ve noticed (besides the added cost per month) is I get a lot more salt creep. Almost instantly things started growing faster, my daily consumption amount almost doubled in 2 months. Added the a and k to the alk and calcium, and started adding the part c. I was just Dosing brs soda ash and calcium. The consumption of ca/alk remained pretty static, and stopped increasing. Growth just seemed to stall out after a while. ![]() I was doing a weekly 5g wc, maybe every 3-4weeks really deep clean and do 10g. Lots of coral growth and decent sized colonies. ![]() I have a 40b with a 40b frag tank attached, probably 60g total water. My personal experience with trace elements is they work when you have a large coral load consuming them, and at the point water changes start to become uneconomical and a real pain always mixing saltwater etc. I know from previous studies that silicate is rapidly depleted in my tank, presumably by sponges (the reason I dose it), by diatoms, and possibly by the GFO that I use to bind phosphate. This water sample was drawn one week after the last dose of silicate. I boost the concentration to about 200 µg/L of silicon equivalent once a week or so. I dose silicate (as sodium silicate solution) to my aquarium. We cannot really tell much, unless there is a substantial excess. The Triton LOD = 0.4 µg/L), so having none detected may be fine. Cobalt is present in natural seawater at roughly 0.006 µg/L. We cannot really tell much, unless there is a substantial excess.Ĭobalt (Co). The Triton LOD = 0.9 µg/L), so having none detected may be fine. Chromium is present in natural seawater at roughly 0.3 µg/L. Binding to organic matter, for example, can alter the bioavailability of iron.Ĭhromium (Cr). Iron is also a case where the form is critical, and ICP cannot distinguish form. I’ve not yet seen a Triton test result for a real aquarium sample that had detectable iron, but that doesn’t mean these tanks are necessarily deficient. This sample was taken more than a week after the last iron dosing, and none was detected as it gets depleted in the meanwhile. I dose iron, and when I dose it I boost iron to roughly 1-2 µg/L, which would be detectable. The natural iron level varies a lot with depth, but surface seawater may have only 0.006 µg/L. That is an interesting area to pursue since this sort of test is the only way to do studies on organic iodine levels. Triton also detects organic forms of iodine, so when some folks (maybe especially those not doing water changes or skimming) get very highly elevated levels of iodine, it may be organic forms they are detecting. So it does not surprise me that it is depleted since I do not supplement. I also know that iodide and iodate deplete in my aquarium based on kit testing I’ve done in the past. Many people have had that same experience. ![]() I don’t generally think that dosing iodine is useful for me based on my experience in dosing it for years, then stopping and seeing no difference. But Mn is biologically important and I will consider it. Detecting none suggests it may be depleted, and is another possibility for dosing, but I have less confidence that this one is really seriously depleted since it is so close to the LOD. Triton can just barely detect the natural level of manganese (0.17 µg/L) since their LOD is 0.12 µg/L. The zinc is about spot on, so there’s not much to say about it. Still, detecting none suggests it may be depleted, and is another possibility for dosing. Triton can just barely detect the natural level of vanadium (1.8 µg/L) since their LOD is 0.9 µg/L. I may consider adding some molybdenum as it is biologically important. I don’t typically add any trace elements. Molybdenum is low, and if that is true, it’s an interesting and potentially important result. ![]()
