I'm still struggling with PH and TA. I realize the two Spa waterfalls into pool will raise PH and the new plaster will also do this. My CH has been fairly constant and currently 250. With the rising PH I'm needing to add acid on a regular basis and this is lowering the TA, so also needing to raise TA on a weekly basis. Seems like my situation likes to stay closer 80 TA instead of 110. I do have some scaling but only right around the spa/waterfall feature. Any suggestions how I can reduce the number of corrections I need to make and create a more stable environment?

There is nothing wrong with having a lower TA ... in fact if you leave it lower, it will help to hold your pH from rising.
Where did you see a recommendation of 110? Recommended Levels shows a recommended level of 70-90+ or even lower (60-80) for SWG because the SWG tends to pull the pH up as well.
Just continue adding acid to keep the pH in check. Maybe occasionally test the TA, but don't worry too much about it.
The "scaling" you see on the waterfall could just be due to evaporation of the water when it is off leaving behind the calcium. Post a full set of numbers and we can see if anything could be adjusted to help:
FC = x
CC = x
pH = x
TA = x
CH = x
CYA = x

Just to add a little to what jblizzle said, the primary reason your PH is constantly going up is because your TA is so high. Let the TA come down until it either gets down to 60 or the PH stabilizes.
Thanks. The recommended test kit (TF-100) says 100-120 for normal pools. My other stats. FC 3, CC 0, CYA 30. My PH varies by day but I try to keep it between 7.4 and 7.8.
Works for most pools but many SWG pools do better with it lower. Take TA on down some more as Jason and Jason have suggested.
I don't have a SWG pool. But in general I think both of you are right, 110 is on high side and causing extra PH rise for me. I'm lowing it down gradually and see where PH becomes more stable.
I just mentioned the SWG levels to point out that a TA level of 60 is still within recommended ranges. You may stabilize above that level anyway.
