At my favorite LFS here in the Detroit area. They mostly have crappy rock, but every now and then they get something like this (18 lb piece). I've got a 35 gallon going with Southdown and 2 pieces about 1/2 this ones size curing. I hope that in the next couple of months to find another 15-20+ lb piece. I like big pieces (like most people I think ... oh and I am talking about LR
) rather than stacking many little pieces.
Heater issue: The live rock touches both the front and back of the glass. So I can't put it down more. I've tried many things. As a background, this is just a temporary nano so that my wife would see how beautiful reefs are and let me get my 75 gallon. She agreed about 2 weeks ago!
