After several days, I am back to using a normal amount of bleach per day. I won’t be buying the brand of bleach that gave me problems for those few weeks.Ok, back to original basis on the thread. I have a new brand of bleach. After two days of use I am back on a basic schedule of using about 4 ppm of FC per day. I am pretty confident in saying that I was correct about the bleach being compromised in some way and not at a full 10%. But I will give it a few days
Thanks for everyone who had input on this.
