MarcoRocks Reef Saver Rock are cut to offer a smooth, flat single surface. Foundation Rock is recommended to be used under any rock work at the boundary layer between the glass and rock display. This design allows the second layer of your scape to safely “float” above this bottom layer, promoting healthy flow around the rock work and over the substrate. Foundation Rock can be siliconed to the glass if desired.
Another aquascape option is placing the rock flat side up for a shelf look.
