To be honest, a 5gal would be better off without one, and just do water changes. IMO.

Agree'd with this. Regular water changes are your best bet for a 5 Gallon tank. Pretty rare to see a protein skimmer on that little water volume (without a sump too).

If you are dead-set on one, I would go for the smallest of the Innovative Marine nano skimmers. They work awesome.

I currently use the Midsized skimmer on a nano and It works awesome.
