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.

The quantity of sand needed will vary depending on the filter size, but it can be anywhere from 150 to 650 lbs.. Prepare the Sand Filter. To get started, place the above ground pool sand filter and pump on a level footing close to the pool. Remember to keep them away from any areas that are prone to standing water.
