My aquarium has thick "Euro Style" bracing that won't allow the AquaChef to slide over the rim with the suction cup in place. What should I do?

With a wide aquarium brace or rim, remove the suction cup from the screw on the mounting bracket of the AquaChef. Slide the mounting bracket over the tank brace until it has cleared and re-install the suction cup onto the screw. Tighten the suction cup down against the wall of the aquarium.
