Just tested today using my new TF kit:
FC - 1
CC - 0
TC - 1
pH - 7.8
TA - 90
CYA - looked straight down in tube, dot never went away, tested twice just in case, 0???
Salt - 3300
The pool is 15,000 gallons, gunite, built a little over a year ago. We are in Cocoa Beach, Florida. We have a Goldline Aqua-Rite SWG and a cartridge filter. The water looks clear. The chlorine has been testing at 0 with my old kit (4 test drop kit the builder supplied me with). I keep upping the SWG % but it hasn't had any effect on the chlorine level. It's at 80% now. I'm guessing that's because of the lack of stabilizer? Last summer I kept the SWG at 60% and the chlorine level was in the middle of the yellow color gradient, I don't know exactly what number, I just looked for the color to fall in the middle where they told me it should be. I took my water to be tested at a pool store the beginning of last summer and they told me to add stabilizer, I haven't added any since. What level should I keep the stablilizer at, 60-80?
Any other problems that you can see? The pH is a little high, I tested before I added acid. I usually add about 1 quart every 1-2 days, does this seem right? I try to aim for around 7.2, because I know it's always rising with the SWG. I don't have a pool service and have kept it up since we got it, but I had no idea there were more than 4 tests I should be doing! I'm so glad I found this forum, it has been very helpful just reading the posts so far. I'm really enjoying learning all about pool chemistry, I only wish I would have found you all last summer. Thanks for the help!
