Need some advice. My pH is pretty stable at 7.6 but my TA wants to creep up from 80 to about 120 (right now). I've searched and read the posts online about how to increase pH without increasing TA, then bring both down with muriatic acid. I created adapters for two of my return jets to aerate the surface, as seen in the picture, and pretty much leave them in all the time. The issue is, no matter what I seem to do or how long I aerate, pH doesn't seem to want to come up. What am I doing wrong or are there any other options? Thanks!
