I've looked around this forum for a while, but this is my first post.
The pool runs on bromine.
The sun breaks down the bromine rapidly, so this morning I put 2 trichlor tablets in the chlorinator to try to use less chlorine bleach. My understanding is the chlorine activates the bromide.
This evening I tested the chlorine/bromine level with the OTO test that comes in the TF-100. The pH was normal, 7.5. The chlorine level was about 4, but in the next several minutes it got darker and darker. Now it's a dark orange color.
I did a little research and it seems the color change is due to CCs. That would suggest I have over 10 ppm of CCs!
Just yesterday morning I tested the pool with the FAS-DPD. I had tested it the previous evening as 11 ppm, and in the morning it was 10.5 ppm, so I would say it passed the OFCLT.
But most importantly, both FAS-DPD tests showed only about 1 ppm of CCs.
How could the CCs jump up so quickly?!
Any suggestions on how to handle it?
Thanks
