I have a new pool (completed June 14) Plaster, SWG 11,865 gallons. I have constant PH rise and go through a Gallon of MA or more ever couple of weeks. I added acid on Saturday and brought the PH down to 7.4 today when I tested it was up to at least 8 (the test kit only goes to 8) so in hopes of stopping the every other day addition of MA I am planning to go the borates route using Boric Acid.
FC 2 TC 2 PH 8 (added acid today to bring it down again)
TA 80, CH 190 CYA 60. Water temp 86.
According to the Pool Calculator I need 28lbs of Boric Acid to bring me up to the recommend 50 level. I have ordered the BA from the chemistry store and the test strips from TFTestkit. I understand that I add the BA slowly, brush like crazy and run the filter for 24 hours. I do have a couple of questions though:
1. Should I turn off the SWG when adding the BA? If so, how long to leave it off?
2. How long after adding the BA is it safe to swim again?
3. Since it is getting late in the season (even here in Central Florida) should I just wait to spring to add the BA?
Thanks for all the help!
