I started my first 55 gallon tank about two months ago. I let the tank cycle for about 3 weeks. Checked for the salinity and tested everything else and water quality was perfect. Added about 30 lbs of live rock. Did use tap water though to start this tank and added drops of prime. Slowly added fishes in- clowns and a damsel. They got ich and died because I wasn't sure at the time what it was, so didn't have time to cure them. So I did a water change, tested everything and results were fine so decided to add in 6 snails, 2 tangs, a puffer, and 2 more clowns. About a week later they all got ich again and I tried to treat them w medicine. Didnt work and they died within a couple of days. HELP!!! I don't know what to do next. Should I start this tank all over again!? Take everything out and use ro
water only?? Need a stronger filter? Protein skimmer?
