Ornamental water gardens and ponds are enclosed ecosystems, sometimes factors like fish load, uneaten fish food, leaves, sludge and unwanted debris may disrupt the balance. Leaves, grass clippings, algae, uneaten fish food, fish waste, and decaying plants all contribute to build-up of sludge which is not only unsightly, but unhealthy, as it consumes oxygen. Pondworx activates immediately and will begin to break down muck and sludge into an odorless gas that will simply escape out of the water column unnoticed.
