Hey Guys, my hot tub is a bit out of wack and I was curious what my next step would be. I just drained & refilled a few weeks ago so I'd really like to try and avoid doing another drain.
At some point in the past few weeks, I lost track of both my bromine level and pH. The pH indicator in my k-2006 currently turns purple when I test it. I did baking soda a week ago because my water was around 7.0 and now it's the purple color. My bromine level on a stick registers dark green (above 20ppm). I tested for bromine on the k-2006 by measuring FC, but FC comes back at 0, with only some slight discoloration around the DPD powder sitting at the bottom of the tube. What should my next step be?
