Hello just start new tank 4 weeks ago, so everything is looks fine exept the corals die.
Tank don't have any thing toxic, exept PO4 that slowly go down every day (I put vodka in my tank). Only thing is kh13 and Ca 520 showing in the test, so question is this numbers gonna go down or do I need to put some chemicals to drop it down? I did't test magnesium lvl test kit is expensive. I changed 25% of water in next day test showing same numbers. Any suggestions? or leave it alone? Currently 5 fishes in there looks happy.
