I've been playing around each day with my new Lamotte ColorQ tester and trying to get all the chemicals right. I went from the following on 12/28
FC 0.11, TC 0.11, pH 8.1, TA 86, CH 257, CYA 40
I've been struggling on getting that pH down and I added a little too much muriatic acid after those test results and put a chlorine puck in the hot tub for the night. To my suprise, I wound up with these results 24 hours later:
FC 5.92, TC 5.92, pH 6.6, TA 15, CH 309, CYA Didn't measure
Is that mostly from the puck? I'm heading to the store tonight to get some bleach and stopping the puck insertion idea due to what I believe to be the cause of most of the variance here. Am I correct on that?
