Last fall I had a fiberglass pool installed .. I got to swim in it twice before it was closed. I had the people who installed the pool open it on May 9th.
after they shocked it, I waited 24hrs. and tested with a taylor test kit. Cl is 5ppm; Ph 7.5; CYA 10 ( added a little stabilizer and need to wait a few more days to retest) My Ca hardness is low about 140-150 and TA is 140 as well.
I see the recommended levels for Ca (fiberglass pool) is 220-320 My question is: Any problem to gradually raise this with Cal Hypo before switching over to bleach?
What about the TA? I see 70-90+ is recommended. how much + is ok (again I'm at 140)
btw the water looks nice and clear
