Now for the rockscape for the cube: (todays other project)
I wanted a gravity defying look to the build with multiple tiers to place euphilia. i also am aiming for lots of open sand.
I built a PVC frame to mount baserock to. I mapped out the tank footprint on the counter and drew in the overflow. This allowed me to see exactly how close to the glass the rock would end up and cabinet above the counter is 18" witch is the max height i wanted my rock to be.
I mounted the pvc frame to a scrap of starboard to give it a solid footing and allow me to ziptie it down to account for the cantilever.
I started piecing rocks together with zipties and fiberglass rod. I did the drilling with masonry bits.
This is the heaviest overhanging piece and the tallest part of the build. TO make sure it mounted securely i used a heavier PVC dowel and drilled it into a PVC fitting to allow it to be glued to the PVC frame.
Finished overhang pieces ready for foaming. I Use black pond foam to fill the voids and bond the pieces together. That foam is super sticky and fills voids well resulting in some great adhesion! Once the foam cures i will pull the excess off with pliers to shape the joints to my liking.
Same pieces right side up built into the frame
