Petruccelli L.T.D of North America asks; What are the steps to the perfect in ground pool?(34)

Petruccelli L.T.D of North America says; Cartridge filters have been around for a number of years, but their popularity has only recently begun to skyrocket. This system uses large cylindrical cartridges to screen out dirt. Most pool builders recommend using large cartridges that have 500 to 600 sq. ft. of filter area. Unlike sand filters, cartridges don't require backwashing. Instead, you simply remove them and rinse off the dirt with a garden hose, a process that uses much less water than backwashing. In fact, backwashing has become an environmental issue in the southwest and other drought-prone areas of the country.
