Water Temp-68F

CC-.2ppm
pH-8.0 (will add 1gal Muriatic acid and retest tomorrow)
TA-130ppm
CH(hardness)-300ppm
CYA-75ppm

I think I did them right but that hardness number looks huge. Will post tomorrow's readings as well. Thanks

Well, FC is on the low side for CYA=75. That explains the CC > 0. You'll want to check the "Best Guess" table and go toward the high side on FC. Generally though, it's common when FC is good to STILL have a trace of CC--.2 if you use the .2 measure, .5 if you use the .5 measure. Not a big worry though. Just remember that you need to keep your FC levels matched to the CYA level. I THINK 60-90ppm of CYA calls for 5 - 10ppm of FC--so you want to be at 7 - 9 ppm, not 5. IMHO

pH is high and you need to lower it. Aim for 7.5, start with one QUART rather than a gallon of muriatic. DO THIS BEFORE ADJUSTING T/A!!!!!!

After pH is 7.4-7.6, measure T/A again. It should be 125 or below which is in range--130 is just a TAD high but the pH of 8 is responsible for that. (I won't explain why here--just for now accept that they are connected).

You have a Gunite pool: Recommended Calcium for that is 200-400ppm --you are perfectly dead center. DON'T MESS WITH IT!

OTOH, I think 68 degrees is too d*** cold to swim in!
