Pool sand filters work by forcing water through a bed of specialized filter sand that traps dirt and debris. Water enters the top of the filter tank, flows down through the sand media, and returns clean to your pool.
Yes, a pool sand filter can be too big, causing poor water clarity due to insufficient backwash velocity and channeling. Proper sizing should match your pump's flow rate at 15-20 GPM per square foot of filter area.
Backwash your pool sand filter for 2-3 minutes or until the water in the sight glass runs clear. This typically happens when your pressure gauge reads 8-10 PSI above the clean starting pressure.
To use a pool sand filter, run the pump on 'Filter' mode for 8-12 hours daily, backwash when pressure rises 8-10 PSI above starting pressure, and rinse after each backwash. Regular operation maintains clean, clear pool water through mechanical filtration.
Pool sand filters require regular backwashing when pressure rises 8-10 PSI above starting pressure, chemical cleaning every 6-12 months, and sand replacement every 3-5 years for optimal filtration performance.
Sand filters work by forcing pool water down through a bed of special filter sand that traps debris and particles. Water enters the top, flows down through the sand layers, and exits clean at the bottom through lateral tubes.
