Hello,
First of all, THANK YOU for your site. I began by reading everything I could from your site years ago. We finally realized we didn't need to do anything but keep chlorine added to the pool on a fairly regular basis, and our pool water stayed clear and clean looking.
Now I write because I decided to check everything over with a TF-100 kit (years old) before we put a cover on the pool, and found things might not be as balanced as I thought. Mainly I wonder if the cya reagent is not working. I began by checking the FC and pH before adding chlorine in order to shock. That began the journey to figure out how much chlorine I needed to shock. The FC first registered - none. So, I tested the CYA. The black dot never disappeared. It got smaller, but was still visible. So, I decided to just throw a bunch of chlorine in and see what was left in the morning. 3.5 gallons of 7.55%. There was a lot of chlorine in the morning. Waited till the afternoon on this very sunny day. Still registers at 20ppm. Here are the rest of the numbers:
FC 20
CC - forget because I was interrupted. Couldn't remember if I had dropped the reagent in, but thought I had. However, it was pink
again. I didn't want to use all of the chemicals, again, so I just dropped 3 more drops in, and it turned clear.
TA 100 (blue to yellow, rather than green to red - supporting lots of chlorine is still in there)
pH - above 8.2
CYA - smaller dot, but still visible when tube was completely filled. But with the chlorine lasting so well... maybe the reagent isn't still good?
Although we are in Indian Summer, I don't know that we have many more days to adjust anything. Should I just cover the pool and start over in the spring with a new kit, and working to bring the pH down?
THANK YOU!!!! for being there!!!!
