Not necessarily. Depends on what your situation calls for. Here is a few questions I asked myself when I decided on my filter.are bio wheel filters the best?
FYI, the off gasing thing for planted tanks is only applicable if you are adding dissolved CO2 to the tank. Otherwise, excess surafce aggitation isn't a bad thing.
Check on the fluval 105. Nice filter. You might even be able to find a cheap 104 still around. It is a canister but remember that you will need more space to put it somewhere, they are much bigger.
Biowheels are fine, though I have never had a problem in 5 years with my aquaclear filters, and no issues with biofiltration while not using one.
