Do you think I may need more backing soda since I am only at 100 now? Perhaps it will take another day or two to register. Maybe since I am adding so much acid it is keeping my TA from raising??

Any help would be apprecaited.

Hi, Dan,

Yes, Alk will move up and down somewhat as you move your pH. That's ok. Testing after 24 hours of dosing is adequate.

Alk of 100 is fine for now. Go ahead and keep your pH in line as your priority and then adjust your Alk as you need. Maybe let it get back down to 80 or so and then bring it back up around 100 but keep you pH in the range you have been all along.

Rising pH in a new pool is pretty well a given as is rising pH with an SWG. To my knowledge you cannot put in too much acid or baking soda...it's far more important to keep your parameter in the ranges suggested.

I think you'll start to see some reduction in your acid consumption soon but I do not have a good feel for when that will occur.
