Bleach not staying in pool?

[h20man]

I checked my CYA & it was @ 7!! Didn't think just warm water can eat up CL as fast as it's been going...pool is @ 85 deg.
FC 0.1
TC 0.2
CC 0.1
PH 7.3
CYA 7
TA 178 - high
CALC 385 - high

dumped in stabalizer & re bleached tonight w/ 2 gallons 10% , we'll see tomorrow

my next question is w/ my ALK & CALC being so high , how can I add muriatic acid w/o dropping my PH too low, maybe I should stay put?
thanks
