Borate test strips seem to be just about worthless!
Q1: Shouldn't the K-1517:BR match the K-1515:FC not the K-1515:CC???
Q2: My CH is rising. Is it part of the TA/PH equation?
PH goes up, bring it down with muriatic acid.
TA goes down, pump it up with bicarb
Still working on where I want this pendulum to stop swinging, but hadn't expected the CH to keep rising.
Q3: (can't count) I added enough 20 mules to get what the pool calc said would be 42 ppm. I didn't want to overshoot and hadn't received my test strips yet. Test strips look like it could be between 50-80 or >80, but really the swab doesn't look like any of the pictures.
Is there a better Borate test? Yes! Yes! Yes! Please????
Q4: (just getting wild here) Fore the "Suggested Goal Levels"
Would you suggest a 400Gal Spa would be better served with the TFP goals or a "Traditional Spa" goals?
Not sure if the calc takes into account the 102F temp when doing the calcs
