Do fish tanks really need filters?

Mechanical filtration traps such particles as plant leaves, uneaten food, etc., allowing them to be removed from the tank before they decompose into ammonia.
How do I choose a tank filter?

Flow rate is measured in gallons per hour, or GPH, measured by the amount of water that will run through the filter in one hour. We recommend that the filter has a GPH at least 4-6 times the tank volume. For example, a 20-gallon tank should have a filter with an 80-120 GPH.
Do aquarium plants keep the water clean?
Every aquatic plant cleans water. They filter out minerals, carbon dioxide, ammonia, nitrates and nitrites. This filtering of the water helps keep the water clear and clean. If ornamental fish inhabit the pond, aquatic plants help create a habitable environment conducive to fish growth, health and protection.
