Can you put a 20 gallon filter in a 10 gallon tank? - Quora

If the budget allows, I would recommend canister filters. Your tank is on the large size, which requires a lot of filtration. Canister filters have the best filtration in real term, even when the Gallon Per Hour rating on the other filters are higher. Considering your aquarium size, I’d recommend two (instead of just one) canister filters. For example, you could do two x EHEIM Classic 2213 which give you total 120g manufacturer rated filtration. If your aquarium will be heavily stocked, get something higher rated such as 2215 or 2217. If the budget is a problem, you can also get two large Power Filters. Additional filtration can be obtained by install sponge filters on the intake of the canister and power filters.

Different Types of Aquarium Filters:

1. Power Filters
These filters are often hanging on the back of the fish tank, and creating a waterfall as the water is filtered and thrown back into the tank. They are fairly cheap, and they are the most commonly used filters for this very reason. They also have down sides, which include the noises (waterfall, as well as the motor). The intake and outflow of most power filters are fairly close to each other, which makes the intake continue to take in a lot of water which was just filtered. Power filters also have limited filter media, which makes biological filtration a less strong point. While it might be a good choice for small- to medium-sized fish tanks, personally I would not recommend a power filter for anything more than a 30 gallon (or 110~120L) tank that is heavily stocked with a lot of fish. You may however use two or more power filters for a single large fish tank, but it defeats the strong point of being cheap. is one of the best power filters available.
