So I had my pool redone about 3 months ago. I used to have a fiberglass pool, now it's a quartz/plaster.
Something Ive noticed is before, I basically did zero maintenance, and everything worked out. I dropped a tablet in about once a week, and had the water tested every few weeks at the pool store, and they said it was perfect. I literally went over a year without putting any acid in. I only added tablets and shock maybe twice a summer. i did this mainly because I knew I was going to have the pool and equipment redone in the near future.
Now I test my pool regularly myself, and I find the PH is always wanting to get near 7.9-8.0. From my reading, the target is around 7.6/ I probably use about 2 gallons of acid a month. I also find myself adding chlorine a few times a week.
Is all of this a result of going from fiberglass to plaster?
Also, what is the downside of letting the pool hover around 8.0 for PH? I feel like I'm fighting a war I can't really win, and I would be better off just trying to keep the PH below 8.0.
