Pool filter cartridges can run for about 2,000 hours for a filter pump. Usually filter cartridges have to be replaced once every 1 or 2 years. The life of the filter will be less if you enter the pool with suntan lotion, deodorants, mousse, styling gels, and other damaging chemicals.
1 You may also want to add a high quality algaecide to the water at this point. 2  Run your filter 24 hours a day and backwash 3 or 4 times a day for quickest results. 3  Green or cloudy water will quickly clog a filter, therefore you may have to backwash your filter many times a day until the pool clears. The pool will never clear up if the filter is not working properly 2  ! Once the water does clear up, you will most probably see debris on the pool floor (dead leaves, algae, etc.). 3  If there is only a small amount of debris present, you may want to vacuum it up using your own pool vacuum system.
