Hi! We are first time pool owners in Ohio. The pool came with the house, it's inground, vinyl liner, 27,300 appx. gallons, Hayward GM 245 sand filter. I have been slamming for 5 days now. The first day there was a noticible change in color, from black to murky green, but we seem to be stuck on the murky green color. Before slamming I added CYA to bring up to 30 and Ph to bring to a 7.5 Our current readings are this:
TA 100 not sure if i did this right I got 10 on the test so 10 X 10??
CH 90 same thing 9 X 10??
CYA is still not showing on the test but it was 0 before we started and I added 1.5 lbs of stabilizer to get a 30
CC tuned yellow??
Help!!! I have raised the FC level to as high as 23 last night with no change. We are running the filter now for 2 days, should it be on pump only? I back washed the filter once, how ofter should we be back washing? Appreciate any and all advise. Thank you!!!!
