Hello TFP,
So It's hot here in Phoenix, really hot, I think the high yesterday was 118F O_O. I think I have the water mostly balanced, however my CSI is pretty high and I'm worried it's going to cause scaling.
I think my fill water has high TA, so the TA is always going to be creeping up, not 100% on this though. For the last few months I've been putting in ~32-64oz of 31.45% MA in the pool about once a week to keep the PH and TA down, however my TA has been hovering around 90-100ppm for a while. I haven't tried to lower it more because I've read a lot of posts saying it will go down on it's own over time and that 90-100ppm isn't too bad anyway. However now I'm wondering, with a combination of the pool water being high, and the high pH/TA at the end of the week, is that making the CSI too high as well.
So my thought is that I should lower my TA to around 60ppm (while keeping pH around 7.6, using the aeration method, etc) that way, even if my pH gets to around 8.0 for a couple days the CSI will still be in the lower range.
You can check my poolmath logs in my profile, but here is my most recent chemical tests:
FC - 6.5
pH - 8.2 (Put in 64oz of MA after this was taken)
TA - 90
CH - 475 (taken 1 month ago
CYA - 50 (15 days ago)
Temp - 87F
CSI - 0.82
What are your thoughts?
