Is specially formulated to help eliminate floating insects from swimming pools, ponds, and other decorative water features. Its unique, non-toxic formula is made with common household ingredients and contains no pesticides or harsh chemicals. By reducing the surface tension of the water, Aqua Pool Guard prevents many surface-dwelling insects from remaining afloat. Once they lose the ability to stay on the surface, they sink beneath the water where they can be filtered or vacuumed away.
