Unfortunately we don't have a magnet holder for the wavebox for anything thicker than 3/4". Your tank is about 900 gallons and would likely need 2 extensions. You could use the older rail mounts possibly, the other option would be 2 6508 masterstreams, these could be pulsed to create a wave with the 7092 or 7096. I assume the tank is acrylic and perimeter braced so you would need to drill the bracing for either the masterstreams or the waveboxes with rail holders.
