Hayward offers a wide variety of pool care products and filters for home use. If you have a Hayward cartridge filter, regular cleaning is necessary to keep it working efficiently. Hayward pool filters trap dirt, debris and algae present in your pool water. A clogged filter means the pool pump has to work much harder to maintain water flow through the system. Commercial filter cleaners can remove most dirt, debris and oil present on the filter, but algae growth requires an acid bath. Muriatic acid, also known as hydrochloric acid, can kill any algae growth on your pool filter.
Step 1
