Canister Filters?

I know this topic has been talked about many, many, many times.

I'm not new to keeping tanks, but new to canister filters, I have 2 other tanks (20/25) that have carbon filters, but this time i have a 46 gal bow tank and i'd like to try a canister filter this time.

I've read about them but still confused. What kind should i get for the 46 gal? Then attach an air tubing to an air stone in the tank? Is that how they work? The canister then sits on the tank stand? I'm clueless.

If you have pics of yours can i see it?

I'm learning alot from you all,
Thank you,

The canister filter operates on a siphon principal and must be below the tank. It may work sitting on the stand, but is better down under. A motor driven impeller forces water back to the tank. Because it's a closed system, water flow (gallons per hour [GPH]) is determined by the size of the motor and speed of the impeller. There is no air line involved.

I have a canister filter and its not very impressive but seems to work. My canister filter needs to be a certain distance below the surface of the water three or four feet.
For my visual comfort I added a small underground filter I just love the bubbles.

I have a canister on my three largest tanks, they (the filters) sit on the floor (= below the tank). There are many brands to select from, but whichever you decide on, get the filter rated for your tank size.
