Since 4/27/16 we've been slamming the pool. Bought a Taylor test kit. Water has cleared very well but we're just not getting to 100% clear like we hope to be. Appx. putting in 5 gallons of 12.5% chlorine daily according to CYA chart. Backwashing nightly and brushing in morning and night when adding chlorine. Put DE in filter. Vac a few times but sediment just settles back in same spots on bottom of pool. Have had rain which added to water to pool but we did add a bit of well water too.

Overnight test is losing bt 2-4 ppm FC. Decided to stop slamming and let the chlorine drop so we can start heating and swimming next week. Should we still be slamming instead? Seems like SO much chlorine.
Also, we do have phosphates which I'm told eat up the chlorine so is it possible the phosphates are eating chlorine at night and not organics. I mean how can algae be in there STILL?
