I lost a couple fish due to ick or what ever ya call it…anyways I have 1 clown and snails and a emerald crab and a cleaner shrimp , the last clown is probably doomed…he’s getting smaller but no white spots. I’m not getting any more fish until this aquarium gets fixed. I do have some softies in there…nothing major. What would be a good process? I figured I’d wait to see the clown’s condition over the weekend. Ideas? It’s a 12 gallon. I did test for a lot of parameters…Alk is high, nitrate at about 5…all others are good….
