What is the expected life span for CYA? How long should it last before I need to add more CYA?
I have a Taylor test kit and find it hard to read CYA. I filled up the CYA test window before it really became cloudy enough to obscure the black dot. No reading here, but it is less than 30. I have added some CYA about a month ago but it appears my CYA has dropped back down.
Any advice is appreciated, thanks!
FC = 2
TC = 2
Ph = 7.6
TA = 80
