Pool Maintenance


 Do not add chemicals if the pool is occupied. This can cause skin or eye irritation. Concentrated chlorine solutions can damage the pool liner. In no event is Polygroup®, the buyer, or any other party liable for costs associated with the loss of pool water, chemicals, or water damage. Keep spare filter cartridges on hand. Replace cartridges every two weeks. We recommend the use of Polygroup® Filter Pump with all of our above-ground-pools. To purchase a Polygroup® Filter Pump or other accessories, visit our website or call Polygroup® Consumer Services.

 What should I do to maintain my pool?

1. Check and adjust pH and chlorine levels daily using required chemicals. 

2. Check filter output daily. If flow is reduced, see Pump Troubleshooting Guide.

3. Check filter for leaks. If leaks are found, tighten all connections, check O-rings for damage and liberally lubricate O-rings with silicon lubricant. See our O-Ring Care and Tips section for assistance.

4. Check seams in pool periodically. Minor repairs may be made with the dry patch kit. Wet patches can be found at your local pool supply store.

 Residue will build up on the cylindrical filter, as well as in the filter basket. This residue will cause a blockage in the suction system, which will result in reduced pressure in the entire system. When the pressure is reduced, the pump has to work harder to filter the water through the system. If the blockage is left unchecked, it could result in motor burnout, leaving your pump useless. The best way to clean a filter is to remove it from its housing unit and rinse off the residue with a high-pressure water hose. Performing this simple maintenance will extend the life of your filter.

To keep your pump and filter working properly, perform weekly preventative maintenance on the unit.

How to clean your filter cartridge: 

1. Unplug the power filter, then do the following depending on your filtration system type.

  • For SFS filtration systems; Remove the lock top by turning it counter clockwise. Remove the strainer basket and filter cartridge.
  • For SFX filtration systems; Remove the top cover by sliding it away from the pool. Remove the strainer basket and filter cartridge.
  • For CP or RX filtration systems; Remove the Seal Top by turning it counter clockwise. Remove the filter cartridge.
  • ​For RP filtration systems; Remove the Seal Top by turning the Seal Top Retainer counter clockwise. Remove the filter cartridge.

2. The filter cartridge can be cleansed of coarse dirt and debris by pressure washing inside and out with a garden hose. Make sure to wash between all pleats of the filter cartridge.

Fine particles of dirt are easier to remove from filter pleats when the cartridge is dry. Therefore, after hosing the cartridge, allow the filter to dry and carefully brush, but do NOT scrub the pleated surface areas. Cleaning and scrubbing a filter too vigorously will wear out the cartridge much faster than if it is hosed off correctly.

3. Sunblock, body oils, lotions and algae can form a coating on the filter pleats that may not be thoroughly removed by hosing. Such films of oils and/or algae will rapidly clog up the filter's pores, greatly reducing filtration. It is imperative to remove such materials from the filter element as soon as possible.

To remove oils, we recommend soaking the cartridge in a solution of 1 pound of trisodium phosphate (or any other strong detergent) to 5 gallons of water for up to 12 hours. Trisodium phosphate is available in many supermarkets, hardware stores, or janitorial supply stores. After the oils have been removed, rinse the filter cartridge to remove any dirt. If algae growth is a problem, add 1/2 pint of pool chlorine or 1 pint of liquid household bleach to the cleaning solution an hour before removing the filter cartridge from the solution. Thoroughly rinse the filter cartridge before replacing it in the filter case. Check the pool chemistry to determine the cause of algae growth.

4. It is necessary to replace the filter cartridge on a regular basis. Calcium or mineral deposits may build up, contact your local pool supply store to ask about additional filter cartridge cleaners or treatment for calcium or mineral deposits.  Filter cartridges may be purchased at your local retailer or at our online store.



The following items are required for proper pool care and are available from your local pool supply store:

  • Test Kit: Used to check chlorine and pH levels.
  • 1-inch Chlorine Tablets: Used to disinfect pool water and help control algae growth.
  • pH Control Chemicals: Used to adjust pH levels Up(Soda Ash) or Down (Acid).
  • Algaecides: Used to eliminate algae.
  • Superchlorinator aka "Shock": Used to destroy combined chlorine, ammonia, nitrogen and organic compounds.
  • Leaf Net with handle: Used to remove leaves, trash, insects, etc., from pool. This is included with the standard maintenance kit or deluxe maintenance kit.
  • Chlorine Dispenser (supplied with filter): Used to dispense 1-inch Chlorine tablets ONLY.

1. USE THE TEST KIT DAILY to check pH and chlorine levels. Adjust accordingly using the required chemicals. Excessive levels of chlorine or low pH levels will damage the pool liner.

2. The pool can be cleaned using the maintenance kit vacuum (either powered by SFS system or hose).

3. Using a foot bath near the pool, washing off your feet prior to entering the pool will help keep the pool clean.

4. Well water often presents problems with water chemistry. If you must use well water, take a sample to your local pool chemical supplier for analysis before adding ANY chemicals. Well water often is high in iron, which can turn pool water to a brownish color.

5. Use the number gallons in your pool to calculate the amount of chemicals you will need to correct the pool water. It is recommended to use a 5-gallon bucket of water to mix and dissolve your chemicals, then applying directly to the pool water. Follow manufacturers label directions on all chemicals. Check our Pool Water Capacity section for assistance.

 Most pool supply stores will test your pool water for free and advise you of what chemicals are needed and the correct amount for your pool. You will need to tell them the pool capacity in gallons. 

IMPORTANT:We cannot over-stress the importance of proper and adequate daily chemical treatment. Chlorine and pH levels must be maintained at all times. The pump and filter alone will not prevent algae from growing in pool water; this can only be done by maintaining proper chlorine and pH levels at all times.
  • Maintain a pH level between 7.3 and 7.8
  • Maintain a chlorine level between 1.0 and 1.6 ppm (parts per million)
  • Superchlorinate (Shock) your pool at least every other week
