I am having a hard time raising my TA- am I supposed to add a few lbs at a time? or all at once?
CYA=60
FC=6
PH=7.2-7.6
TA=50
CYA=60
FC=6
PH=7.2-7.6
TA=50
Baking soda can be added by spreading it across the surface of the deep end of the pool.
From the TFP Pool School - Recommended Pool Chemicals page:
With a TA of 50, you shouldn't have to add too much right? Are you trying to sneak-up to about 60-70? As long as your pH is remaining stable, be cautious about raising the TA too much.
Is your ph already holding steady? If so, as others suggest, no need to change it. That's what its job is.
If you do add more, use pool math to figure exactly how much and start in 1/3 increments.
I mix anything I add (except cya & bleach) in a 1 gallon bucket of water then pour it slowly over a return.
Nope, it works the opposite. The higher the TA the faster the pH change. I keep my TA at 50. As it goes any higher the pH rise moves quicker.the pH keeps going up, so I was thinking raising the buffer (TA) should keep the pH from going up all the time? pool is plaster.
How much is it going up and at what rate i.e. Daily etc...?

From the documet you linked:really? I thought the point of TA is to reduce pH fluctuation- this is the first place I am hearing the opposite

An exacerbating factor is that higher bicarbonate alkalinity can cause a more rapid upward drift in pH, due to the gradual loss of carbon dioxide from the water.
