My tank is clearing up.Thanks for all the advise.I think what happened is that I put too much coral additive in one cap per week .I put 3 caps in at one time with just two frags.It was like pouring gas on a fire away it went .I had a full blown algae bloom in two days.I was also running my lights 15 hours a day.Seachem Clarity is clearing up my tank.The first day i put it in I had to clean my filter pads 5 times.Thanks
