Sand Filters. For sand filters on inground pools, I like to use a 30" tank diameter, which has a 4.9 sq. ft. filter surface area and holds 600 lbs of sand. For small pools (under 20,000 gallons), I might advise the next size down (24" tank) if the budget is tight. But never go smaller than a this for an inground pool. Cartridge Filters
Jan 28, 2003· The size of the sand placed around the screen influences the amount of water that can be withdrawn from the well, particularly if the well is a pumping well.

The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging.
