Conclusion

A canister filter is a great choice for a 20 gallon tank because it is very efficient at cleaning the water and it is also very easy to maintain. Canister filters can be placed under the tank or behind the tank, and they come with all the necessary hoses and fittings.

Canister filters are also very quiet and they do not produce any noticeable vibration.
