OK I just got my Taylor test kit and gave it a whirl....
FC: 15 ppm (way too high right?)
TA: 170 ppm
CYA: > 100 ppm (I think the pool guy got a little carried away)
Calcium Hardness: 230 ppm
So I was thinking since pH is a tad high and TA is high, I would add ~ 2 cups of muriatic acid (it's only a 2000 gal spa, maybe even a little less)
I think I just have to let the CYA go down with time from splash-out, etc... Is that correct?
And I think likewise the FC level should come down with sunlight, which is abundant in our area at present. I was just going to turn down the SWG to minimal until FC gets back in line (which I think might take a while with CYA so high)
Does that sound right? Am I way off on anything (or everything?)
