Waterbear, I saw your response on Maxsrents post about tweaking your water balance to get your acid use down to 6 oz. every six weeks. If you don't mind me asking, how did you reduce your acid use? We have a 6,550 gallon FG with Reliance SWG, which I love. Currently, I'm adding 8 oz. of acid each week, which isn't bad, but I would love to reduce the acid maintenance as much as possible.
We don't have any water features, so aeration isn't really an option to lower the PH.
