Have a pair of channel catfish,large mouth bass and bluegill in a 240gal set up. The catfish have velvet (spots) Have treated with Organi cure. It is for salt water but was told by the local fish expert that it should work for fresh. Have the water temp set at 76 degrees. It has been almost 48 hours and other than what seems to be more action from Kit and Kat there are still spots on them. ???
