I'm a rather new pool owner. I had a question regarding the relation of phosphate removers and CYA levels. Specifically, is there a link between the two. Up until yesterday I did my testing at the pool store. I fell victim to the recommendation of using phosphate remover because my FC and TC levels were at 0. Once I did, the water turned murky which I discovered here is a common occurrence. I am in the process of running the pump to clear the water, cleaning the filter every time the PSI jumps 10.
Deciding that the stores won't fool me twice, I have been studying here and have bought a Taylor Test Kit from Leslie's and recently did a test. 2 days ago, prior to using the phosphate remover, my CYA (Stabilizer) levels were at 60 ppm. Doing it on my own today my CYA level was well over 100.
My results were:
So, is there any reason why I would be getting a much higher CYA that what the store test reported 2 days later?
