Personally, none of my tanks (maybe with the exception of the smallest ones) are filtered only to the rated amount. For example, I have a community 29g tank that has a Penguin 150B (rated for 30 gallons) as well as an Eheim Liberty 150 (rated for 30 gallons, as well) so I've really got double the filtration needed. I have another 29g tank that will be a starter tank for a Jack Dempsey cichlid. The tank has a Skilter power filter rated for 55g tanks, as well as a Fluval 204 canister, which is rated for 40 gallon tank. So, this tank is receiving three times the "recommended" filtration amount. So you can see the point I'm trying to make...adding more filtration is definitely a good idea. I don't think I would replace your filter entirely. It may not be the best brand, but if it physically works it can be an asset to your aquarium. You might want to add a second HOB filter or, preferably, some sort of canister filter to the tank.
