Ran out of #13 so I went to Leslie's for a CYA test. Guy put some in the test cylinder and proclaimed it "okay". I asked what the reading was and he looked down the tube again, lifting some slider, and said 30-40. What is your opinion on the trustworthiness of pool supply store testing?
I ask because I added CYA as if I was at 0 to get it up to 40ish. For some reason I equated it with chlorine as being "used up" over the winter. Then I read here again and was reminded it is not. I have a hard time believing it really was 0 to begin with.
I am opening up the pool for the season and it was pea soup with waterbugs and leaves. I cleaned all the leaves and dead bugs out, shocked for several days until CC was 0 in the morning, and am not checking overnight-falling FC. But the water is very cloudy. I have a slime bag on and broke down and added a "Natural" clarifier (made from chitin so I can feel better about myself even though it is probably no better for the environment than the synthetic stuff).
Opinions on the reliability of Pool Store testing?
I will have complete results tomorrow other than CYA.
