Natural Bird Bath & Fountain Protector

CareFree Enzyme Natural Bird Bath & Fountain Protector uses natural and human, pet, and wildlife friendly enzymes to clean bird baths and fountains and keep water crystal clear. This enzyme based formula breaks down biofilm and sludge while keeping the water safe for birds by breaking down the organic debris and mineral deposits that act as a food source for algae and slime. Use as directed, overdosing may cause foaming, and some extremely dirty bird baths and fountains may take several weeks to clear up.
