Cara's Pool School — gnats

There are a two "bug scenarios" common to pools -- gnats and swimmers. In the case of "gnats", they tend to accumulate on the surface or throughout the water and can be treated with a chlorine-based shock treatment and collected in the filter with the use of a common clarifier. In the case of "swimmers", it is usually recommended to use a polyquat/preventative algaecide and a chlorine-based shock treatment. In either case, your local and trusted pool professional should have options available to steer you toward a bug-free pool.
