Its a known fact that kanamycin ie kannaplex and furan2 can be combined and are synergistic. Kanna gets absorbed through skin and furan does not and mostly treats external infections. I have iused this combo many times. Infact it used to be made by aquatronics the same blend. You use full strngth in both. Furan 2 by itself in marine tank is not that great. Kanaplex in combo is wonderful!! Standard freshwater dips. Ro water at same temp as tank with same ph ie small buffer for 3 to 5 minutes kills lots of parasites and gives fish lots of relief. I like to rotate this with quick cure dips. Ie 1 tsp of quick cure for 3 gallons of sea water in bath for 30 to 45 mins airated. As for my credentials. Well I'm no chemist but you can check me out. June tank of the month and in large reef tanks bith of two systems of 30k gallons. In addition I just treated 3 baby genicanthus personatus with these antibiotics and posted about it in reef fishes under that fish and my large tank blog.
