Is there any difference or is one better than the other between Fritz Copper & Copper power? I have used copper power several times and the problem keeps coming back in month or two Ick I believe no one can tell me for sure but it appears to be a form of ick! Thanks for any input or other medication I can use in a fish only tank 600 gallons. This is getting tiresome going on 3 years fighting this problem(parasite).
Thanks
