How long to see TA reduction when treating with muriatic acid?

Current chemistry:

FC: 3ppm-8ppm
pH: seems to be rising pretty quickly, takes maybe 1wk to rise from 7.3 to 8.0
TA: 160ppm (I'm dropping pH to ~7.0 periodically with muriatic acid to try and reign this in, but haven't seen much change in the two cycles I've done so far)
CH: 260ppm (I am chlorinating with unstabilised CalHypo until this reaches 350ppm)
CYA: 48ppm (recently diluted from 210+ppm)

So far I've put maybe 2ga 31.45% muriatic acid into the pool, but haven't seen any movement in TA...
