I'd recommend a standard filter that hangs on the back of the tank. Hagen has a good brand. Canister filters are fine too. However, they're roughly 3 times the cost and take more time to clean. The Hagen will essentially do the same job.
Determining the filtration needed is simple. The tank will need a filter system that circulates 4 times the volume of the tank in gallons every hour. A 55 gallon tank will need a filter or filters that turns over roughly 200 gallons of water per hour. That's called the gph
. The information is listed on the filter package. If you're a diligent water changer and remove and replace at least half the tank water every week or so, you'll have a healthy tank.
