Protein Skimmer for 30 gal.tank.

[Aquattro]

The visijet is about as useless as a seaclone. Keep in mind that when a skimmer is rated at 100g, it's probably only good for something about half that. The bak pak is probably your best choice of the ones you've suggested. Buying the cheap $100 skimmer is just going to frustrate you and you'll end up buying the bakpak anyways. If you can't afford $200, go skimmerless until you can. That way you don't throw a $100 skimmer in the garbage.
