Well, I've decided to close my pool this year after last year being such a bear. I'm now trying to get my water balanced in order to do that. I had to be out of town for about 3 weeks so testing didn't get done. When I did to it, my numbers were the most out of whack they've ever been.
I immediately turned off the SWG since it looks to be working overtime! I say ? on T/A because the test turns blue, not red; in fact, it went from blue to yellow. So I took this to mean that there was none and put in the required amount of baking soda to bring it to 80. Then about an hour later I put 1 1/2 cups of acid in to bring down the pH.
Two days go by and I retest (yesterday). The FC has come down to 21 but the T/A still turns blue...no yellow any more though. The pH is still 8.2. I'm getting ready to go out and put another cup and a half of acid to lower the pH. Can anyone tell me what the problem is on the T/A? The pool is being closed tomorrow. Is this going to be a problem if it doesn't get resolved?
Thanks for your help!
