I can't remember offhand which of the reef blogging sites have done pieces on them, but if you search reeftools, reefbuilders, etc. you should find something - I have most of them I think, in my fb feed so the stuff just shows up and I get confused too easily which one posted what.

I thought there were some newer posts too somewhere but offhand I can't find them and unfortunately my time is up, I gotta run to work.
Maybe someone else can fill in with more deets?
