So before my tank crashed during sandy power outages I had no problems keeping coral. I had zoanthids all over and mushrooms. At the time I was using IO reef crystals. I started my tank up again in January and decided to switch to Red Sea coral pro salt on the advice of friends. I put a zoanthid frag in last month and died a week or so later. Last week I put some mushrooms in and they have yet to open up fully. My salinity is 1.024 nitrates and nitrites are 0 and ph is 8.2. The only things different in my tank than before the storm are 6 mangrove plants and the fact that I am using Red Sea salt. Anyone have any thoughts as to why my corals and doing well?
