Hello Everyone, I think my tank has Ich or some kind of parasite in it. My Angle fish two lions and trigger have all died Very sad to look at my tank empty. They all came down with white spots all over and my lions ended up with real cloudy eyes. I have been dealing with it for about 3 weeks. I tried Ich treatment, did alot of water changes, and tried to soak the food in garlic, but nothing seemed to work. My tank was a 180 gallon FOWLR with 75 gallon sump. I am just wondering what the process is to start over? Do I just leave the tank with the same water in it for several months before I add new fish? Do I do any water changes? Should I treat my tank with anything? After 3 months or so, will I have to re-cycle my tank again or just slowly add fish? Also, I have noticed that there are some aiptasia starting to come back. Will these die off with no fish or food being added to the tank over the next few months? Thanks for your help or advise you can give. I just want to make sure I do not go through this again.
