Hello everyone! This question is for my work pool that I take care of at an apartment complex, not the pool in my signature...
semi-public (about 20-40 swimmers a week I would guess... really not super busy)
Sanitizer 3" tabs trichlor
ph 7.5 (added 8 cups soda ash today to get here)
I have been taking care of this pool for about 10 years, and every year, the whole swimming season, I am constantly adding Soda Ash. I buy it by the 50lb bag and go through a few of them for the swimming season (picked up my second bag today) I would say I add approx. 8 cups of soda ash every 5-9 days. The pool place I buy from finds it strange that I need so much of it, as normally everyone needs to keep on adding acid, not soda. My tap water is on the higher end of PH so it's not from that, although I try to do weekly unnecessarily long back washes (in attempt to keep CH and CYA down mainly).
Any ideas on making the PH more stable would help me, and since we're doing so well on my pool (even though mine is liquid bleach) I figured you all are my best chance of help.
