Ok just used the tf-100 to test my water. My FC =0.25 and my CC=2.5 for aTC of 2.75. My CYA has been at least 100. I stopped using trichlor. The pool calculator says I need over 500 oz of bleach is that right? I'm sure my readings Re correct. I thought if CYA was so high that the chlorine would not be that low. I'm new to this please advise
Thanks
Thanks
