If you cant find the Malachite green right now then you can use the stuff in the super ich cure. Most of its a mix of M. Green and Formalin. It CAN be mixed with the Tripple sulfa without issues. I would dose on the lighter side or half dose of the Super Ick cure. Then do the full dose of the Tripple sulfa. I feel the tripple sulfa is the more important of the two of these. Be sure to follow the directions of the tripple sulfa completley and do the water changes and repeate dosages as specified. Make sure to fully dose till they say to and repeate if nessacary. The Tripple sulfa will also NOT harm your Benificial bacteria either. Tom may dissagree with my thoughts, and again im betting he is smarter then I am (not to say im dumb lol). You could also just try doing the Tripple sulfa on its own.
