Dave and/or Dan: I assume this reactor is, specifically, a "calcium carbonate reactor". As I begin to research my plans to build my own reactor, would you mind contrasting this design with that of the "Nilsen" style or kalkwasser reactors? I'd be interested to learn more about the advantages/disadvantages of each. I can't seem to find that kind of info through Google, reefcentral, etc. (Yet, I find plenty of DIY plans for both...)
Thanks, and pardon the thread interruption! Looks like the DIY project came out extremely well!
