How much lower than the aquarium should the canister filter be?

Question by yayu: How much lower than the aquarium should the canister filter be? I am setting up a goldfish tank in a "coffee table" aquarium. The base of this tank is about 6" above the floor level. If I set up a canister filter at floor level (about 6" lower than the base of the aquarium), is that sufficient for the the filter to work effectively? Best answer:

The filter should be lower than the bottom of the tank if not water can go into the pump and fry your fish.
