Hi all,
I added CYA about 1 quart 3 weeks ago about a week after testing it was 40. Recently did a 2-3 day SLAM. Checked CYA yesterday was 25.
How reliable is the CYA test with the black dot. Tested at dusk.
FC 2 added shock since
pH 7.2
TA 110
CH 225
CYA 25
Use a solar cover when not swimming.
Has rained a bit so about 1inch extra water since test.
