My 46g planted/tropical tank with swordtails, platys, cories, plecos, and mystery snails has ich. New fish introduced it. I never like to use harsh chemicals in my tanks. Right now I am treating with heat, water changes, and 1 T. of salt per 10g with the intent of increasing it to 1 T. per 5g. I've googled a couple of solutions and have seen people recommending reef safe ich treatment. I've taken all the snails I can find out, but there might be one or two left, plus ramshorns that never go away. Anyone had success with products labeled "natural" or "invertebrate safe"? Right now the breakout is not bad and only limited to a few fish, but I don't want it to get out of control.
