Clean your swimming pools' filter cartridge when the PSI reaches 8-10 PSI above its initial reading when you first put in a new or clean filter cartridge.For spas or hot tubs, establish a regular cleaning routine based on the usage of your pool or spa.

Step 1

Remove the cartridge filter from the filter's housing following the manufacturer's instructions.

Step 2

Use a garden hose to with a straight flow nozzle to wash down the filter cartridge. Work from the top down, cleaning both the inside and outside. Hold the angle of the spray at a 45 degree angle for best results. Clean in between all the pleats.

Step 3

Rinse and repeat until all the dirt & debris is gone.

Step 4

If the filter cartridge is still dirty or has been used in a spa or swimming pool where oils like perspiration, sun tanning lotions/oils are frequently used, then soak the filter cartridge or at least one hour (overnight is more effective) in either A: a commercial filter cleaner, or B: in a solution of one cup of Trisodium Phosphate (TSP) to five gallons of water. or C: a solution of one cup of dishwashing liquid to five gallons of water.

Step 5

Rinse the filter cartridge again, repeat 2-4 again if needed.

Step 6

If the filter cartridge has a coating of Algae, calcium carbonate (residue from calcium hypochlorite), iron or any other minerals, soak the filter cartridge in a solution of one part muriatic acid to twenty parts water until the bubbling stops. WARNING: Failure to remove all oils and cleaning solutions from steps 2-5 above could result in the permanent restriction of water flow through your cartridge filter resulting in a partial or complete failure of your cartridge filter.

Step 7

Rinse the cartridge filter completely and replace it within the filter's housing as per manufacturer's instructions.

NOTE: We do not recommend using Diatomaceous Earth (DE) powder with any filter cartridge. The powder particles will become trapped in the body and will shorten its life expectancy greatly.
