Hi, I found this site about a month ago when my husband let me try my hand at turning our green pool back to blue. He fired the pool svc about 2 years ago and has been taking water samples to the pool store and buying shock at their suggestions but the pool has steadily turned green with algae stains. I've followed the directions I've learned at TFP and the pool is now blue but the algae stains are still there. I had to stop the SLAM because my husband wanted it swimmable for Father's Day and it looked pretty good. But now I notice that the algae is creeping back. Fourth of July is this wkend and I know he will want it swimmable then. What can I do from now till then? Should I add bleach daily to keep the FC at 4 at least? I seem to be losing a heck of a lot of FC overnight. Also, my CH is super high and during a drought in Nevada its not feasable to drain 40% esp since I don't know if the city water is CA free.
Test results today:
CYA 40 (added 1lb in sock day before yesterday when CYA was 30)
Have been using only bleach.
Thank you for your advice!
