ParaGuard™ is the only fish and filter safe aldehyde based (10% by weight) parasite control product available. Unlike highly toxic and difficult to use formalin based medications, ParaGuard™ contains no formaldehyde or methanol and will not alter pH.

Cupramine™ effectively eradicates ectoparasites of both freshwater and marine fish. It is superior to copper sulfate, chloride & citrate: it is non-acidic, less toxic to fish, remains in solution, and does not contaminate the filter bed.

I just wanted to take a few moments and tell you how great your ParaGuard™ is. I have been using it for years and have yet to come upon a problem that it did not solve. It's good to see companies that produce products that do what they are supposed to do.
