I've finally accepted that I have green algae. I was hoping it was pollen. Water has been clear until I brush then plumes up green. I have a inground vinyl SWG. I raised the percentage up yesterday to 50. Normally run around 5-10. Pool is about 15,000 gallons with the Hayward 15 ( for 40,000 gal.) yesterday the TC was 4 and PH 7.5.
Today TC is 11 and ph is 8.2. Is the ph up because I already raised the chlorine and should I adjust the ph now or continue to super chlorinate and leave it alone. Yes, I switched to that about an hour ago. I have not slammed with bleach. I think I can get the FC up with the SWG. Numbers from first test today are
FC 11 CC 0 TA 80 CYA 50 PH 8.2 I had to backwash and add water today after those numbers. I did a ph test and it's still up there. Will wait on the others until a little later. Water is degassing right now also ( if that what tiny bubbles on the side is). I know the CYA is low. I raised it from 25 to 50 since last week. So, keep chlorinating, adjust ph, or what? I think I've been going in circles. Thanks.
