Alright so I have an in ground, well water, decently large pool, not sure how old, but we used it last summer without problems. We opened it up about two weeks ago, and did the usual maintenance to get it started up again (adjusting pH, adding the proper amount of chlorine, adding the right amount of shock, vacuuming the bottom, filtering the water, clarifying the water, etc) and the water is now blue, but is very cloudy. It’s very thoroughly vacuumed, filtered, and chemically balanced. So we replaced the sand in the filter, still cloudy. So we asked a friend for advice and he suggested to add ten pounds of super shock, let it circulate for a couple hours, then shut the motor off and once everything settles vacuum the bottom. We did that, still cloudy. We’re at a loss, and any advice would be greatly appreciated.
