Todd, Collective wisdom here is a whole bucket full of oxymorons.

Here's the deal on whizzeroo bacteria deals. They all claim to perform miracles but will never tell you what's in it. Some have reported good results from bacteria and others have found no change. They never come with a money back guarantee and don't bother asking.

Bacteria is naturally occurring in your pond. Some have said that the stuff you can buy to clean up your septic system works as well (or not at all) as the highly advertised and touted ones.

I doubt that it would harm your pond.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
