So I took my first real reading after adding all the chemicals and such, it has been almost two weeks since then. My FC was very slow to drop and just got to acceptable level today even though my SWG is still set to 0% production.
PH - 7.5
FC - 5
CC - 0.5
TC - 5.5
TA - 80
CH - 290
CYA - 95
My question is regarding TA and CYA. For my TA test the water turned completely blue for a second at 8 drops and then back to green (not sure if there was a different tint or yellowish tint to it). Then it turned red at 9 drops. Would TA be 80 or 90 in this case?
Is my CYA too high at 95? I think my pool may not be 29,000 Gallons after all since most my levels went higher then expected. I did get help form you guys a couple of seasons ago to calculate my volume and the last two seasons that estimate seemed to have worked perfect so I am bit confused. I adjusted my PH to 7.5 two weeks ago and still holding there without adding any acid which is nice.
Based on my adding 25lbs of Calcium Hardness (my CH was 160 at opening) and it rising to 290 I would have a 21,000 Gallon pool but that makes no sense whatsoever. I have been using 29,000 Gallons for adjusting my PH which is spot on and most other readings are a lot closer then this. My pool is free forms (hard to measure) and the builders paperwork states its 34,000 Gallons. To raise CYA from 35 to 95 I added 8lbs of Stablizer, that shows I have a 16,000 gallon pool, does this make any sense? Is there some easy way to figure it out?
