we have a 27 ft round above ground pool with a DE filter - when we opened the pool on Friday it was swamp green - after a lot of bleach and PH minus we have got the water blue - but cloudy. I have used 3+ gallons of bleach - 3 bags of shock and have 2 chlorine tabs in the filter. we have changed the DE 4 times since Friday and consistently bump the filter when the pressure gets to 20. We have brushed the bottom and the sides.
Here are the latest test results -using a stick test
Free Chlorine: 0/0
Suggestions are very much appreciated we are going crazy over here trying to figure it out
