As my signature implies, I am the noobiest of pool noobs. My pool was installed last year, and since then, I have been getting inconsistent and expensive advice from my local pool store. So far, I get my information from test strips and water tests at the pool store, which I understand are unreliable. I ordered a K-2006 kit from recommendations on this page, and I will be receiving it from Amazon in 2 days. I would like to get started on solving my problem before that, if at all possible.
We are experiencing an obvious algae problem, and I responded to it several days ago by shocking the pool. Per the advice of the pool store, I have kept the chlorine levels very high, and the green is not budging. From my research, it appears that I have too much CYA (I'm basing this on the fact that the algae is not clearing up even though the chlorine has been so high). I've also read that the only way to lower CYA is to partially drain and refill the water. My question is - should I wait for my test kit to arrive to confirm CYA levels, or should I drain and replace some water now?
I'm sorry for the lack of details. Like I said, I'm working off of test strips, so I can't give definite levels. I can tell you the chlorine is BRIGHT purple, and the pH & alkalinity appear to be in check.
Any advice would be greatly appreciated! Thanks
