Pool Liner Care

Water Testing Kit

Maintain a proper water pH balance.

  • pH in the 7.2 to 7.6 range

  • Total alkalinity at 80 to 100 ppm

  • Calcium hardness: 200 ppm minimum

Maintain free chlorine residual between 1.5 and 2.5 ppm.

If free chlorine drifts below 1.5 ppm, algae and bacterial growth can take hold more easily and may cause staining of the vinyl liner.

A pH of less than 7.0 should be especially avoided.

A pH of less than 7.0 can cause the liner to form wrinkles and with a greater probability if the water is not stabilized for extended periods. For this reason, it is recommended that all vinyl-lined swimming pools be routinely stabilized so that a minimum of 50 ppm be maintained.

Pre-dissolve slow dissolving sanitizers in a bucket of pool water.

Add the solution to the pool by filtering through a sieve to prevent non-dissolved particles from settling on the bottom, otherwise, spot bleaching of the liner could occur. Always read and follow manufacturers’ instructions given on product labels and containers.

 

Test for the presence of dissolved metals in pool water.

Dissolved metals may cause staining of the vinyl liner directly or combine with calcium hardness and form discolored deposits on the vinyl liner. Follow the manufacturer’s recommendation concerning the use of chelating materials to inactivate dissolved metals.

 

Chemicals should never be mixed together and added to the pool water at the same time.

Certain combinations of chemicals that individually will have no effect can cause bleaching of the liner if the concentration is allowed to remain high in the vicinity of the liner. Always allow a chemical to disperse evenly throughout the pool by means of water recirculation before adding a second chemical.

Do not drain the pool completely for any reason without consulting a pool professional for advice.

The older the liner, the higher the risk that the liner will shrink and not stretch back into its original shape without ripping. Sites with a high water table may also carry the additional risk of structural damage.

Never close a pool without circulating the pool water for several hours after the final addition of chemicals.

Even liquid chlorine can concentrate in the deep end and cause liner bleaching if not sufficiently blended with the rest of the pool water.

 

Use a well-fitting winter pool cover that is tightly sealed around the entire perimeter of the pool.

Pool liners prevent the accumulation of debris such as leaves, worms, etc. during the winter period. Organic matter has the potential to cause staining and/or bleaching of the vinyl liner.

 

Avoid the use of abrasive cleaning agents or cleaning aids.

Do not use steel wool, sharp bristled brushes, scouring pads, etc.

 

Use only the manufacturer’s recommended vinyl liner cleaner.

For removing accumulated soil at water line or other soiled areas, use only the manufacturer’s recommended vinyl liner cleaner.

ALWAYS FOLLOW MANUFACTURERS' RECOMMENDATIONS FOR ANY CHEMICALS USED!
