Best filtration system for 10 gallon nano?

[Beau baker]

So I have a decent amount of experience with saltwater tanks but I've never really messed with a nano tank before. So my question is what's the best way to filtrate a standard 10 gallon nano reef tank? I would something kind of small to hang on to the side of the tank. Thanks in advance
