Hey guys i have a quick question i am setting up my 65 gallon tank and while reading the instructions on the fluval box it said that it must be 4.5 feet under the tank (gravity filter). My tank is hovering right over the ground and i had space set aside it for the filters.

The space for fluval 406

Tank shot
While it working sitting next to the tank???
Thanks so much!!
