I'm thinking of dosing my tank w levamisole to ward of a case of Ich i have going. I'm under the impression it mostly is well tolerated by hard coral, but I was wondering if anyone had experience with soft coral reacting to levamisole. ANy info would be very helpful. I was thinking of dosing about 5 grams to 300 g ratio. I have a 90 g tank with some hard, plenty of soft (torch, hammers, zoo's) and a few chromies and tangs. Thanks
