Yes I do. I have been doing more reading and see suggestions to use both Cal Hypo or Tri-Chlor.

I am leaning towards using the Tri-Chlor because my CYA is low and needs replenished. I also have CYA I can add on its own so I'm not sure which way will be the best.

I need to retest my numbers when I get home, I did not get a chance to this morning before heading off to work. what are the upside/down side to using Cal-Hypo vs. Tri-Chlor assuming I need to add CYA anyway?
