After a recent drain and acid wash, I took over my own pool mx and it's been great so far. It's a 30 yr old, pool, but I've only owned it for seven mos. The previous ownership was pretty lazy and relied on tabs and a pool service...the CH and CYA were off-the-charts high. All my reading on TFP indicates that I should be very careful about additions of conditioner, so I've deliberately only allowed it to get to btwn 40-50ppm since the refill...I figure it's much easier to add more, if needed, than to remove it. I live in S.California and my pool is in a very sunny location (in direct sunlight, nearly all day).
Question #1: Is 40-50ppm CYA enough for this amount of daily sunshine? My normal FC consumption seems to be 3ppm every 2-3 days...I seem to be adding approx 64oz of 10% liq CL every 2-3 days to bump it up 3 ppm.
Another thing I'm trying to get a better understanding of is PH management. My pool has an attached spa that is elevated 2-3 feet above the pool water level. When the pump is running, the spa water spills over into the pool to be recirculated. It really just flows down the face of the spa, as opposed to being like a waterfall. I've been trying to keep my PH in the 7.6-7.8 range, via lig acid additions, but it seems to want to climb right back up to 7.9-8.1 after just a week, or so. According to my chemical addition tracking, I've been adding approx. 32oz of 20 baume (31.45%) MA, weekly, to knock the PH from 8-8.1 down to 7.6...2 drops on the acid demand test and using the Taylor-recommended additions. Is this a normal amt of MA to be adding, based on my pool description?
Thanks!
