Not having a way to measure the bacteria in my pond, I have to go by the fact that it is clear and no major algae growth (more bacteria leaves less nutrients ). Easy to use and have used it for several years in spring and fall. Fish are healthy.

These are a great and easy way to get a head start on Spring and Fall Pond maintenance. They are very easy to add to the pond, and don't seem to bother my Koi.

I’ve tried other cold-weather pond bacteria, but they can be a pain to use and not very effective. This product, however, is a breeze to use and very effective. When I cleaned my pond out this spring, I didn’t have to deal with a lot of leaf or other broken-down debris. I just had to pump the dead algae out. Saved me hours of work.
