Cleaning your Spa and Jacuzzi Filters:
Clean the filters when you notice a decrease in the pressure from your jets, or when the pressure in your filter tank increases by 8 psi from when the spa filter was newly installed.
To clean the spa filter, first remove it from its canister and use a garden hose to dislodge any debris between the pleats. Soak the water filter in commercially prepared filter cleaner, or spray with the same to remove organic material and oils. To remove stains soak overnight in a solution of one quart bleach and 5 gallons water.
Thoroughly rinse the cartridge with fresh water and reinstall it into the canister. Be sure to follow manufacturer's directions for installing the spa filter.
DO NOT use a high-pressure car wash wand, a stiff brush or acid wash to clean the filter cartridges as these methods can damage the filter media.
