Well, if you're looking for a "cheaper" alternative (albeit LONG term, ROI in 12-18 months?), go with a calcium reactor. At 110g full of acros and growing (and likely a lot of coralline), you might be consuming 0.75 - 1dKH/day? At 58mls/day, I'm guestimating that you're currently paying ~$45/mo in Alk alone? You're supposed to dose Ca in equal amount so $90/mo total? Switching to BRS (or other DIY solutions) may bring you down to $60/mo - $720/year? Again, guessing on my part.
Understand that the upfront cost can be daunting but one can put together a decent CaRx system for less than $500 in the used market. The media might cost you ~$30/year going forward. Additionally, it's less work mixing jugs and all. I just change my media once / year -- just set it and forget it!
