FC: 18
TC: 1
Cyanuric Acid: 30 - I know this is a bit low, but it's nearing the end of the season, and I have plenty of bleach
Total Alkalinity: I'm not sure, I don't test often but its probably high like 150. I never adjust it, and have not all season, because my PH is always on the money.
pH: within range before I started to SLAM
I noticed over a a good amount of time, maybe 2 weeks, that something seemed a little off. I started seeing some build-up on the floors and walls, looked to be algae, not a whole lot though, and the pool was not really cloudy, maybe just not crystal clear. I'm in the NE and we have been getting slammed with storms. I know this doesn't help so I have been trying to keep FC on the high side. I also know I probably didn't keep up with it enough previously. A few times when I went out to test/add it got down to 1 or 2 ppm.
Not a big deal though, I'll just SLAM the pool. Anyways started increasing to SLAM levels on Thursday(around 11PPM) and really got it cranked to above 15 consistently on Saturday( I had to re-stock and it was a thing, you guys know). Anyways it's now Monday night and I'm still sitting on 1CC since Thursday, I can not get this thing to budge. The pool is crystal clear and cant really see much or any build-up. Maybe a few spots, but again its been storming like crazy so I can't really tell if its a small amount of algae or just debris stuff from the storm. I brush, run the robot, and backwash daily, but still 1 CC. It seemed like a really small problem, so I figured a day or 2 tops would know this out, but its still turning pink on the back-end of the drop-test.
Anyways, just looking for some advice here, I'll keep it cranked up for the time being, but was looking to get the pool back to a use-able status soon. thanks.
