The site was leveled with 1/4" #10 gravel (Asphalt feed stock) and cinder blocks positioned with the aide of a isosceles triangle fashioned from the cross bars of the prototype Thorens Aquatics Zebrafish Rack. Simply bent some wire through existing holes. There was even a center hole to aide in lining up center rib of the cinder blocks. This made placement of the blocks go much quicker and more accurately.
One inch styrofoam pads were placed between the cinder blocks and the tank. This protects the tank and allows for some slop in the placement yet keeps firm pressure against the bottom of the tanks keeping them very stable.
The tanks in place and leveled.
The Bug helping Dad level the tanks. Has his fishy colors on today.
