About a month ago I added 3 corals to my tank: sunflower, hammer coral and elegance. They were doing fine but a week ago the corals started to receed. The elegance is almost dead by now and hammer is looking really bad.
Nothing seems to be wrong witht he water, and I had it checked for a 2nd opinion:
Nitrite: 0
Nitrate: 0
Calcium: 410
Alkalinity Kh: 8
Salinity: 1026
Ammoniak: 0,15
Phosphat: .03
Brown algae is growing everywhere, and there is no way to get rid of it. (also some kind of algae is growing on the zoa)
Its a 90 gallon tank, there is a protein skimmer. 2-3 days ago I added caulerpa as I thought it may be phosphate, however the algae are still there and I cant see phosphates on water measurements. Also I had change 10% of the water 2-3 times in the last weeks.
The tank gets light from 10 am to 10 pm, gradually intensifying and then changing into blue at the end of the day.
Any ideas what could be wrong with the tank? I really would like to save those corals.
