So I am hoping that I can get some guidance as to what to try. I have a 55 Gallon that is over a year old. I have been taking it very slow. 4 months in added a clown. month latter cleaner shrimp. 4 months latter Brown Tang and Yellow Tang. 1 Month latter Brown tang died no idea why. Shortly after Shrimp died. No idea why. Two weeks latter Yellow tang got Black Ick. Moved him and the clown to QT tank. Tang Died after RODI water dip from stress I guess. I also keep loosing snails and conchs fairly regularly. I have 1 torch in the tank for 4 months and that is doing good I think.
I test weekly and Calcium is low - Working on that slowly. PH is good, Nitrate good, Phosphate is good (although its probably high due to hair algae issue I am fighting, but not testing high). DKH is good too.
I have no idea what the issue could be or what to look for. Any Ideas?
