The following are characteristics of Modernism: 1  Marked by a strong and intentional break with tradition. 2  Belief that the world is created in the act of perceiving it; that is, the world is what we say it is. 3  There is no such thing as absolute truth.

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.
It only needs to be replaced every 5 years. Both salt and sand are not included, but both can be purchased at a local hardware store. Maintain your peace of mind with the two year warranty. Upgrade to the Intex 3,000 gph Sand Filter and Saltwater System Krystal Clear Filter Pump for bigger pools and quicker filtration.
