What are the guidelines for using the bleach? I am finishing up the chlorine tablets that I had purchased. The mineral cartridge is out. I've got some Borax but also have not used it as my pH seems right on. Today's test:

Ch = 1-2
pH = 7.5
TA = 210ppm

Let me know about using the bleach and the borax. I did not test CYA today, but I will and report back. Thanks...
