I have been slacking on keeping an eye on my CYA because I am running low on the chemicals to test. Have had some rain and added a bit of water due to backwashing a few times so decided to run a test this morning.
My CYA level a couple weeks ago was 50, now it appears to be lower than 20 which seems like quite a significant drop to me.
I *did* just add some acid to my pool to bring down my PH, could this be skewing the CYA results?
