I have an Intex 32ft X 16ft Sand Filter and Saltwater System and I feel like the pump can't circulate all the water. Also with that I have a well and that means hard water. A pool guy told me to use a calcium reducer so that my sensors won't have as much calcium build-up. However it hasn't really worked. My pool was crystal clear for the first month I had it but with the hot days it seems like I am lost on how to get it back on track.
