VEVOR Sand Filter Pump for Above Ground Pool, 13 in, 3500 GPH, 3/4 HP Swimming Pool Sand Filter Pump System, Krystal Clear with 6-Way Multi-port Valve & Strainer Basket, Easy Installation for Pools
Why am i having to backwash my clean pool 3 times a day.? The pool is clean. Chemicals are in normal range. When i backwash the water coming out is just cloudy. It only takes 30 seconds to clear up.
Backwashing is only necessary when the system is first put into use and when the sand filter needs to be cleaned.

Over time, impurities from the muddy water will remain in the sand, which will affect the flow rate of the sand filter. When this happens, the sand can be replaced.
