Just did my first test with the K-2006C test kit, and I wanted to confirm what I think I need to do.
Test results: 7.8 FC, 0.4 CC, 7.7 pH, 120 TA, 260 CH, 100 CYA in 78 degree water.
Here's what I think I need to do:
Stop using the 3" chlorine tabs in a floater so my CYA doesn't go any higher
Lower my TA to the 60-80 range
However, the calculator in the pool math app says I'm looking at about 2-2.5 gallons of 20 baume muriatic acid to lower my TA that much, and it shows that would result in a pH drop around 3, which is obviously bad.
Am I doing the calculations wrong? Should I be partially draining and refilling to drop the CYA before messing with anything else?
Something else to note: we did take a water sample to our local Leslie's store to see what their tests said prior to getting my kit. Their test shows the TA at 90 rather than 120 (everything else was much closer to my test). Judging from other posts, it seems like I should trust my kit over the store test, but I still wanted to mention it.
Thanks in advance!
