It was a new pump at the end of last season, well August I put it in. Close to the end, I kept the pool open until October.
I changed the sand since it was 6 years old and my kid let go of the winter cover taking it off, we had about 30 gallons of leaves in the bottom of the pool we vacuumed out, couldn't get the sand filter clean after that.
Changed the sand yesterday...still waiting for the cloudy water to go away, pumps been running 28 hours straight, water looks a little better but still not great. Hopefully by tomorrow night it's better
