Nope, it rest up against the glass, it smooth on the back.cvp7900":3nomxiv3 said:That looks awesome! So the rock in the back is concreted to the glass?
RustyReefer":20nfmzth said:The rock is crushed oyster shells,sand,crushed coral,hermit shells, and white type 10 concrete. I started buy making a mold of the back of the tank buy building a copy of it out of wood. Than I covered it with poly so that the concrete would not stick to it. After mixing the concrete I covered the mold and let it harden for 4 days before moving it into cureing tubs where it sat for four weeks, water changes three time a day, untill it stoped changing the alkalinity of the water.
