BRS made me laugh with this video. They were claiming that you can save a lot of money now by getting one of these new calcium reactors. Which I guess are a little cheaper than a GEO but not much. Then they put all these high-end accessories to go with it. In the end, I don't see much savings. Not to mention they are talking about put one on a nano. I'm not an expert on Nano, is it possible to fit enough livestock in a nano tank to justify a calcium reactor? I mean you are still looking at over 1k just to get started.
