So I noticed Ich first on my 6" clown loach. I dosed the tank with Mardel Coppersafe. Now a week later I'm noticing more ich than I originally had AND noticed it spread to my oscar. The temp is up to 82f and I don't wanna go any higher. I gave the coppersafe a full dose. Mardel claims that it stays in the tank for 1 month but surely they can't expect a person to wait 30 days for it to kill off ich.....Just based on the ich lifecycle I shouldn't be seeing new ich spots on my fish right?
