I have a Taylor k-1005 kit. The test results with this kit are. FC 3.0 Ph 7.8, Alk 90, CYA less than 30. However the test strips and store test say my cya is around 50. I am having trouble maintaining my chlorine and having to add chlorine every day. My pool is clear, and spreads nearly the entire day in the sun. I'm thinking that my kit may be correct and I need to add more cya. My over night test show that the chlorine is stable. What are your thoughts?
