Healthy Ponds AquaSphere PRO Large Pond Cleaner, 1-Million Gallon Treatment, Model# 51150

The AquaSphere® PRO treatment system is an all-natural dispensing system used to improve water quality and clarity in large size ponds and bodies of water up to 1-million gallons (approx. 1 acre). The 6in. dia. sphere features a patented time-release system that's designed to deliver a proprietary blend of natural bacteria and enzymes into the water continuously over a 30-day time period to help consume excess nutrients. The corn resin-based outer shell is completely compostable in the sludge layer of the pond, breaking down over time so there's no need to remove the sphere at the end of its 30-day treatment life. The cleaner is ideal for use in commercial applications including golf courses, commercial real estate, homeowner associations, retention ponds, parks, zoos, recreation facilities and fish hatcheries. Safe for pets, fish, people, wildlife and plants.
