Test results Friday,
CYA 50 (may be a touch more - tested after 5 days)
I wanted to up the pH as it's been staying at 7.2, with children in the pool very often, and one of my returns pointed to the surface.
I added 28 oz of borax to raise the pH to 7.5. Tested Saturday morning. pH=7.2
This isn't the first time I've tried to raise my pH. But my pool seems to like it at 7.2. Water is perfectly clear, and the girls don't even bother to wear their goggles in the pool. They open their eyes underwater and says it doesn't sting at all. Very comfortable. No redness whatsoever. So, should I say to heck with it and let it stay at 7.2, or is it a little on the low side and should I do my best to raise it a bit. Also, the fill water from the tap reads a pH of at least 8.2.
