Hey all. Was hoping that some of our chemist-oriented brethren can assist with some info on this.
Yes, I admit...I have so far this season been using expired Cyanuric Acid Reagent. My question is...how can I tell if it has actually "gone bad"? When using it to test for CYA levels, does a "bad" reagent tend to give you HIGHER readings? LOWER readings?
I have tested using this expired CYA, and the result is "45", which is ideal for my pool.
BUT:
1.) I've noticed a LOT of chlorine usage. I'm putting in more daily than I ever have
2.) I took a water sample to Leslie (Found out they don't do the test kit CYA bottle/shake test anymore...ugh) and they use the testing cartridges. Their results showed CYA at 35. But not sure if I trust the cartridge tests.
I plan to purchase more/fresh CYA Reagent. Just interested in learning! Thanks for your help and replies.
