Product description

Pond Worx Pond Bacteria

Leaves, grass clippings, algae, uneaten fish food, fish waste, & decaying plants all contribute to build-up of sludge which is not only unsightly, but unhealthy, as it consumes oxygen. Pond Worx breaks down muck & sludge into an odorless gas that will simply escape out of the water column unnoticed.
