From what others say here, you do not need one for a tank that small but that it would still benefit you to have one. I have no idea how much of a benefit it would be though.
I am contemplating adding one to my 20g as I have been reading great things about the AquaticLife nano skimmer that is now $48.00.
Skimmer or not, youll likely need to bump that PWC
up to every week for a small tank like that.
