Pond Boss Pro Block Bacteria — Treats 5 Acre-Ft., Model# 54290

This blend of live bacteria and enzymes is specifically designed to improve water quality by reducing unwanted nutrients in your water. It clears out pond- or lake-bottom debris like leaves, grass clippings, dead and dying plants, excess food and other organic matter. These bottom-lying materials are referred to as the sludge layer and are responsible for bad odors and low oxygen levels. Each 5-lb. block treats up to 5 acre-feet of water. Non-chemical treatment is safe for fish, plants and other wildlife. U.S.A.
