hi,
I have a few corals in my tank that are not doing well at all, and several that are doing very well. All corals have been in the tank for several weeks. It is a 24 gallon with metal halides, levels are
Ammonia 0
Nitrite 0
Nitrate less than 10
pH 8.2
Phosphates 0
SG 1.024
I do a 10% water change every week but I do not add any essentail elements or anything.
THe corals that seem to be doing poor are a green open brain (at bottom of the tank, has lost a lot of color recently), green star polyps (located in high flow but still not opening), and a frogspawn coral (half way up th tank, low flow). I feet marine snow every other day. I have another frogspawn located at the same height that is doing great, and xenia, mushrooms, and zoos doing well too. I have had this light bulb for about 4-5 months, is it time to replace it or are my corals not getting the requirements they need. PLEASE HELP!
