How often does everyone check their Cyanuric acid level? I got a new kit, tested my level.. found it low, raised it, tested again.. then we had a lot of rain a while back, tested the level it was low again, raised it and tested it again. now I'm out of reagent and was ordering some more. But that stuff is kinda pricey.. anyhow I'm curious at the frequency I should be testing my CYA. Is it a quarterly test? Once a month? Twice a year?
