could you please inform us on how the aquarium will be braced as we are concerned about the 30mm glass used for sure.
Also for the backgrounds. Both sides please use black to cover glass and back side will be blue
Also for the overflow box will be needing 2 holes in the bottom to accommodate two 2" PVC pipes to get water into the sump below
size of the holes should be sufficient to accommodate the 2" PVC connector pieces.
