When referring to a canister filters head height for example an FX6 is 10.8 feet, does that mean vertical and horizontal? I'm questioning this because I set up a 54 gallon corner tank that has a few African Cichlids in it. The tank is set up behind a large piece of furniture. I'd like to upgrade and put a fx5/6 on it and have the hoses run behind the furniture from the tank to the filter that will be on the floor about 7 feet away hidden. Then I can have the filter sitting with easy access to it so I don't have to move the furniture to service the filter. Will this pose a problem with efficiency or overall performance? I realize an fx5/6 is overkill for that tank but if there's a decrease in flow, it just may work out. Also if it does work what would be the maximum distance to run the hoses from tank to filter? Any thoughts or suggestions would be great.
