I'm working on a similar project for my 105G tank. I used the extruded polyethlene- i.e. sheet garage insulation. I've been using the West Systems epoxy 105+206 hardener, and industrial sand. the sand is brown-i'll be using some of the Rit dye for shading/color. I'll be buying another batch of the epoxy-the "b" size- since the stuff has a long shelf life there won't be any problems with leftovers. |
