How Do You Use A Sand Filter In A Salt Water Pool?
You can use sand pool filters in a salt water pool with no problems at all. The filter will function in the exact same way with salt water that it would with traditional chlorine methods of pool sanitation. Sand filters use a specially graded sand as the filter media. The water enters the tank through the diffuser. As the water goes down through the bed of sand, the dirt and debris is trapped between the grains of sand. When the water reaches the bottom of the filter, it enters the laterals and is returned to the pool. The salt water system will not affect this process.
Sand filters are one of the most common types of pool filters and work with both salt water pools and chlorine-based pools. Sand filters work by allowing pool water to pass through them but preventing debris from passing through, thus filtering the water. The result is crystal clear water for swimmers to enjoy. A standard sand filter removes particles and debris up to 40 microns in size, and filters 15 to 20 gallons of water per minute. The great thing about sand filters is that they actually improve in efficiency over time, because the debris that it traps actually begins to block out debris as well. Monitor the pressure gauge reading for the pool on a weekly basis. When it displays a pressure reading of 8 to 10 lbs. over the initial clean reading, you must clean the sand filter. Backwash the sand in the sand filter once every four weeks. Backwashing is cleaning the debris out of the sand by reversing the flow of water. First, shut off the pool’s motor pump. If your pool filter has a
