I posted in this section of the forum about my Calcium numbers. Turns out, there is interference with my reagent when my TC is higher. I added some more drops of indicator, and got 250ppm CH. Anyway...

My test kit is older. I think the reagents for TA and CH are older than the rest. I need to get a new test kit. My TA readings keep decreasing, while my pH keeps drifting up (even with constant additions of acid). I may go back into the pool store tomorrow and get the water tested again. I need to get my CYA tested because we added last week, but I"m out of reagent.

I just don't know which numbers to trust. Numbers are only as good as the tests used, and the people doing the testing. I trust myself, but not my test kit. The pool store...I'm not sure about either. At least the water looks clear and sparkly.
