I have an 18' AG. Here in Texas it may get below 30 just a few days out of the year, so I don't close the pool, I just trim back how long the pump runs and make sure it runs during the freezing temps. However, I always get junk in the pool, and still always having to clean it. So I was wondering this year, can I put a cover on, but still run the pump to circulate the water and inject chlorine?
If I can, do I need to put a pillow in the middle to keep the cover up off the water?
