Do I need to add/replace sand for my pump? Why is sand replacement important?

Sand is used for the pool filtration because it has the effect of retaining dirt from the size of 10 to 100 microns. When using sand, the filter system work and remove all retained dirt and return to the pool with safe and clean water. They are very important in keeping the water clean. Replacing sand regularly and using clean, safe, and reputable sand is very important in maintaining hygiene for your pool.

Sand filters generally have low maintenance needs, depending on the size of the tank, it is recommended to open the filter tank and change the sand once every 3-5 years. When dirt accumulates in the tank for a long time, and the pressure gauge shows 8-10 lbs, it is time to clean out the dirt from the filter tank.

Water filtration efficiency will be degraded if not cleaned regularly and properly. Over the years, water can erode the sand, causing reduction in the filtration function. To tackle this problem, it is necessary to run the filter to maintain the water quality first, and then replace it with new sand to improve the water filtration function.
