Yep ��. I added to get to 80 after my I initial tests yesterday; before I thought I’d be slamming. Luckily my pool is relatively small and, based on my pool clarity, I should have a relatively short slam as well.Mike,
while not impossible you are now going to have to SLAM at a level of 31 and hold it with that CYA amount. That’s going to take a ton of bleach. Make sure your CYA test is correct. I can’t imagine how or why you lost the CYA in the first place. It doesn’t go anywhere except from splash out.
Pool is crystal clear and the CC test often comes up clear or only very slight pink tint. I’ll let it drift as you suggest into the teens. Thanks for the help!Passing a Overnight Chlorine Loss Test at very elevated FC levels is typically quite difficult. The error of the test is 10% when FC is over 10 ppm.
Once your pool is crystal clear with no CC, you will most likely need to let your FC drop to the teens before doing a Overnight Chlorine Loss Test.
