Is a sand pump better than a filter pump?

The cartridge filter can catch finer debris than a sand filter, being 10-20 microns versus 20-40 microns. Because there is less water flow restriction than that of a sand filter, there is less demand on the pump, creating a lower rate of energy consumption, and less wear and tear on your pump.

How does a sand filter work for a pool?

Sand filters work by allowing water to cycle through a canister that contains sand. The water flows through the sand with ease, but larger particles are unable to pass through. Once the debris and other particles have been filtered out by the sand, a pump moves the clean water back into the pool.
