The trick to cartridge filters is to size them right the first time! Here's one time where "bigger is better".  Bigger meaning filter size, not horsepower.  The Hayward® Pro™ Series Sand Filter System with its 16" or 18" tank.  Although the filter may have the "capacity" to filter much more than that, you don't want to be backwashing the filter sand every other day.  When your filter is properly sized & chemically maintained, normal backwashing is performed about every 7 to 10 days & chemical cleaning should be done about 6 to 8 weeks.

Hayward® Pro™ Series Sand Filter Systems are manufactured with high quality ABS & PermaGlass XL™ materials made to last years under normal conditions.  Other X-Stream Cartridge Filter features include:

• integral top diffuser distributes unfiltered water evenly over the sand media bed in a cascading, umbrella-like pattern
