I need a little reassurance, or confirmation that this is going as it should.
I've had renters taking care of my pool with strict instructions to follow TFP protocols. Unfortunately, the renters moved out, and haven't kept an eye on the pool for the past month. I'm not sure what went wrong, but apparently the SWG was/is not producing chlorine, and the pool was almost black when I got here Monday (May 31). I've never seen it close to this bad.
I started SLAM about noon on Monday (48 hours ago)
Initial test was - 0 FC, CYA about 30, pH at 8.0 I threw in about 10 LBs of 93% sodium bisulfate, and started SLAM with target FC 12ppm. I brushed the sides for about an hour and checked FC, added more 10% bleach, and continued checking and adding bleach every couple of hours.
My concern is, I'm not consuming a lot of the chlorine, typically only dropping 2 or 3 ppm (to 9 or 10 ppm) every 2-3 hours. As bad as the pool looked, and with relatively low CYA, I expected to be churning through the chlorine. The pool looks a lot better; it's no longer black, or even green, but very cloudy and I still can't see the bottom.
This is not my first SLAM, and in the past the pool cleared up, at least visually, in about 24 hours. Plus, I re-tested CYA this morning to confirm my numbers were right, and it's barely measurable. The test sample is a little cloudy, but I can see the dot when column is full. How does CYA drop in 48 hours? Should I add stabilizer now or finish SLAM first? If I add now I won't be able to backwash the filter, and I've been backwashing a couple of times a day!
I should add, I've continued brushing and running my robot several times a day.
So? Am I missing something, or do I just need to be patient and stay the course?
