I replaced a powerflo matrix 1.5 hp with a powerflo lx 1.0 hp the filter is sand 23" pro series hayward. I can't see more that 12" into the water so I am not sure if sand is coming in the pool. Last night I turned the pump off to see if anything would settle to the bottom but nothing the water still cloudy. I am using regular bleach and testing the water myself with the k2006 kit.
