After coming back from a long job assignment of two month, I found my the pool green.
I have been shocking the pool with 3 powder plus packages http://www.lesliespool.com/Home/Pool-Ch ... 14676.html
When the pool stayed milky or cloudy, I used targetís brand chlorine and raised it to 15 due to my cya level of 30. After two days of none stop pump circulation the water still milky. D.E. Filter has been back washed two times and no green is coming out. I get some white water that leaves d.e. stains on the cement where the water sat.
Please help me get my clear water again.
The details about my pool: PLASTER 30K NONE SALT WATER POOL IN GROUND /PH 7.4 CYA 30/CURRENT FC 15/ ESTIMATED WATER VOLUME IN POOL IS ABOUT 28K GALLONS. D.E. filter correct size for my pool volume.
I thank you so much for any advice,
George from Claremont California.
