Hey dansdad,
I'm still kinda lost. It would help us all if you would make one post with a full set of readings (FC, CC, TA, CYA, CH). You don't need to redo them all FC and CC should be new - CYA is <30, TA and CH from the last time. also an inventory of all pool chems you have on hand (dichlor - %, Trichlor - %, Cal-Hypo - %, bleach - %, anything else). It may not be OK to throw out the Cal-Hypo. Also the pools present condition.
Thanks
Dave
