Your pool pump can run 6-8 hours in the winter and 10-12 hours in the summer.
Why This Is Important: If the pool is not run for the proper amount of time, it will not filtrate the water through the filter effectively. A pool has a lot of water in it, usually around 10-30k gallons. ALL of that water needs to filtrate, or run, through the filter to clean it. Also if the pool is not circulating and is stagnant, it becomes a breeding pool for algae.
