Sand Filters
A very important part in pool careYou can get up to 5 bag of sand filters depending of the size of your pool
Basically, water flows into the top of the filter housing and makes its way down through the sand bed where the sharp edges of the sand catch the dirt. Sand filters certainly are efficient enough to keep just about any pool clean and to keep a sand filter working efficiently, you must clean it as often as once a week during swimming season. Maintenance means backwashing where the flow of clean water is reversed back into the filter. The only problem being, the backwashed water must be replaced in the pool. The sand in this type of swimming pool filter should be replaced every 3 – 5 years.
