Hope everybody is doing well.
My pool is a little over a year old. In that short period I managed to run my CYA up to approximately 160ppm using Tri-chlor tabs. After wrestling all summer with algae, I decided to empty and refill. Heavy sigh...
Post refill I'm at
0 ppm CYA (Bringing this up slowly)
150 ppm TA
160 ppm CH
65 degF Temp
2.8 FC (Bleach)
-0.1 CSI (per http://www.poolcalculator.com)
The TA and CH numbers make me a little bit uncomfortable because they are so far out of the orthodox range. However, the CSI looks good. I don't want to deliberately add calcium as our tap water is at about 140 ppm and should increase my CH over time. And, I think the TA will drop over time with aeration from the spillway on our SPA.
So, I'm thinking about holding where I'm at on TA and CH. What do you all think?
