Pseudo said:No need to silicone. The weight of the rock is good enough. Some people do seal it thinking that detritus will get underneath it and cause "problems". But it is not true unless the pieces are warped. And even still there wouldn't be a build-up of substantial porportions to do any harm. Plus who the hell looks under the starboard ???

Or just get two pieces of cutting board put it in the middle of the tank. Also Can I just put the live rocks on top of the glass-no boards? Thanks.
