The AquaClear filter is called a HOB
filter or, like the article says, HOTT (hang on the tank). In the article, you can see in the picture that you'll need some room behind the tank for the filter to hang on the rim of your tank. You'll have to make sure the hood will still fit with the AquaClear in place. The AquaClear is a very good filter. A lot of people here like it. But it won't stay as hidden as a canister filter does, under your stand, and it does add a little more "footprint" to the tank.
