I have lost my box puffer and neon dotty to ich. I set a hospital tank (55 gallon) in my basement. I believe my tang and domino damsel also have it for they are scratching or acting odd. I picked up some API super ich remedy. All I have access to at this moment. No copper in town.. I took out all the carbon from the canister filter I am running. I have no media on the ground. What else do I need? Also, do I treat all my fish?
