Coppersafe

I like to use coppersafe as a preventative medicine as opposed to an ick treatment. Once my fish already have ick, I don't find this to be extremely effective in clearing it up. But, it seems to be effective at preventing ick from building up in the tank if you add a little in every time you do a water change (maybe about a 50% dosage in the new water).

For treating ick that has already developed into a problem, I prefer Quick Cure.

Pros: great as a preventative

Cons: sold in relatively small doses if you own a large tank

The best choice for parasites. This clears up Ick better than any other. Follow the instructions carefully and you should be fine.

Pros: Works very well

Cons: Be very accurate with your measuring
