Thanks, Richard. I was jk about the home-brewed acid. I figured it had to be a dangerous process.

I have been an avid reader of the "rising pH" thread and others, and I've successfully lowered my TA from 280 to 120 using Ben's aeration method. But it's a continuous battle because my fill water (from a well) has a TA of 320. I've found that if I add 2 pints of acid each time I top up, I can keep the TA steady. Unfortunately, because of a leak, I'm topping up twice a week.
