Many liner problems are a result of misuse of chemicals.  Prior to treatment, read and follow the chemical manufacturers’ directions and follow these suggestions: 1. Never mix different chemicals together, add one chemical at a time. 2. Dilute or completely dissolve all chemicals in a bucket of water prior to adding to the pool. Always add chemicals to water not water to chemicals. Never use your hand to stir chemical solution. 3. Make sure that the circulation pump is kept running to thoroughly disperse the chemicals. The time needed varies from pool to pool, but you should circulate the entire volume of pool water through the pump at least once. Most pool chemicals are heavier than water and if not dispersed properly will sink to the bottom of the pool and lie against the liner in concentrated form damaging the vinyl. 4. Do not put chlorine tablets or sticks into the skimmer because bleaching of the liner may occur when the water pump is turned off. 5. Never scatter dry chlorine onto the surface of the pool water. Doing so will result in bleach spots on the floor.  Proper water balance has affects on the liner.  1. Keep the pH in the range of 7.2 to 7.6; total alkalinity at 80 ppm to 100 ppm; and calcium hardness at 200 ppm to 300 ppm. pH level above 7.8 mean the water is too alkaline and calcium deposits can form on the liner surface. 2. Keep free chlorine, the most common active ingredient that sanitizes the pool, at 1.5 ppm to 2.5 ppm. If the concentration drifts below 1.5 ppm, algae and bacterial growth can cause staining of the vinyl liner. If the active chlorine concentration is maintained greater than 2.5 ppm, liner wrinkling may occur. This is further aggravated if accompanied by pH levels that fall below 7.0.  Careful cleaning is needed to not damage your liner pool.  Dust and dirt from the air combined with body and suntan oils can form a residue at the waterline which, when baked into the liner in the hot summer sun, can cause the liner to prematurely harden and crack. Leaves or other debris should not be allowed to lie on the  pool floor for long periods of time as they may stain the liner. 1. Scum line dirt should be cleaned off on a regular basis using a cleaner specifically designed for vinyl liners. Do not use abrasive materials to clean the scum line as these will remove the pattern of printed liners and roughen the surface liners making things stick easier. Do not use acid based cleaners because they will discolor  the pool liner. 2. Cleaning equipment used in the pool such as brushes, vacuum heads and automatic cleaners, should be specifically designed for liner pools. Be sure the pool brush and pole do not have any sharp edges that could tear the pool liner.  3. Automatic pool cleaners that remain trapped in one position can damage the pool liner. Never leave them unattended to for long periods.  Off-season care is also important.  1. Be sure all debris is removed from the pool water and that any chemicals added are thoroughly dispersed. 2. At the end of the pool season adjust the water level to the dealer’s recommended level, test the pool water and correct the water balance. 3. NEVER close a pool without circulating the pool water for several hours after the final addition of chemicals, because chlorine may settle in the deep end and bleach the liner if not allowed to thoroughly disperse in the pool water. 4. Clean and vacuum the pool.  5. Use a well fitting winter pool cover, tightly sealed around the perimeter of the pool to prevent the accumulation of debris, such as leaves and insects, during the winter.
