Yes, that helped immensly. Thanks so much for taking the time to post all that. So no Borax at all then? When do you use Borax? LOL. Don't kill me...........I'm sorry for all the questions. I bought a fountain adapter for my aqualuminator today so I'm going to use that (I was going to add some Borax, but maybe I won't). I need to raise the PH before I use more acid to lower the alkalinity again, that I'm understanding. At the pool store, my numbers were 170 ALK and 7.0 PH. I will aerate to raise to 7.2, acid to lower to 7.0, and keep doing that until my ALK is in the target range. Right???
