Got distracted with some other things, and I didn't see some of the advice until this morning. Thanks for all the help!

To start, I'll make sure you know about my pool. It's a 25k gallon plaster pool with a spa. The spa spills over into the pool, so there is constant aeration that I can't really turn off. I also have a water feature that I run sometimes (my wife likes it), so that adds even more aeration. The pool is almost 10 years old, so it isn't a new surface issue. I stick to the BBB method, and do not have a SWG.

Thanks for reminding me, it was actually two years ago. I did the Borates thing, that was a ton of Mule Team I added. To be honest, I wasn't crazy about the taste of the water after, but that's a separate issue. I haven't been religious about testing for borates since, so I'm not sure what the level is now. I honestly can't remember how much it helped stabilize my ph, but it did help. By now, without monitoring it, my ph is raging once again.

I'm thinking it is a combination of the constant outgassing and my source water. But now I'm confused whether to raise the TA or not.
