Adequate filtration is essential. The water passes through the filter, is cleaned and returns to the pool. The correct size of pump and filter is critical. The sand in the filter (if applicable) will need to be changed every 3-5 years although this time period may vary depending on the factors affecting your pool.
Water moves through your swimming pool, distributing chemicals in the water. The aim flow(s) should be aimed 30-45 degrees down. This will give you better chemical distribution and the water flow will not affect the performance of the pool cleaner.
Clean the pump basket, lube O-ring and skimmer baskets weekly (more often if it is windy and there are trees or sandy areas around your pool). The filter must be 'backwashed' for 1-3 minutes (or until water is clear) and 'rinsed' for 1 minute bi-weekly during summer months. If you are using a non self cleaning Salt Chlorinator, clean the Chlorinator cell weekly. Also, clean the surface of the pool with the pool skim net when required.
