1. Maintain proper water balance.
        a. pH in the 7.2 to 7.4 range (extremely important).
        b. Total Alkalinity at approximately 100 -120 ppm.
        c. Calcium Hardness at a minimum of 100 ppm.

2. A low pH of less that 7.0 should especially be avoided since it can cause the liner to form wrinkles. There is a greater risk of wrinkling if the water is not stabilized with a cyanuric acid level of at least 25 ppm.

3. Chemicals should never be mixed together and added to the pool at the same time. Certain combinations of chemicals that individually have no effect can cause bleaching of the liner if concentrations are allowed to remain in the vicinity of the liner. Always allow a chemical to disperse throughout the pool by means of water circulation before adding a second chemical.

4. Never close a pool in the Fall 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 bleaching if not properly mixed with the rest of the pool.

5. Avoid the use of any abrasive cleaning agents or cleansing aides (ie., steel wool, sharp bristled brushes, scouring pads, etc.)

6. Use only manufacture's recommended vinyl cleaners for cleaning accumulated soil at the water line or other soiled areas.

7. Maintain a 1.0 to 1.5 ppm chlorine level and correct any algae situration as quickly as possible. Algae inhibits your liner's ability to remain resilient and shortens the life of the the liner. Always use algaecides as recommended to avoid bleaching and discoloring.
