Pool is blue, but looks as if someone poured milk into it. Used it all last summer, with no problems. Over the winter, it got quite a bunch of leaves and debris in it. I have gotten all the leaves out, but can't seem to get the really small particles out. Wondering If I should drain it. Or if there is a way to filter better. I have been running filter 24/7. The filter and the SWG are brand new, and not for sure which direction to go. Any help/direction would be greatly appreciated.
