I'm about to the point of building Mr reef structure. I have a bunch of .375 acrylic rod and flat stock, a couple .400 masonry drills, and a whole bunch of live rock. Once I have the rock in the desired configuration I want to somewhat lock them in place. Looking through the long list of reef epoxys I'm a little lost. I have the luxury of letting it cure before for a hour or two before ssubmerging the structures. Any and all sugestion welcome!!
