Anybody know of a DIY Protein Skimmer that would work for a 30-gallon aquarium.I've been looking around for a protein skimmer but they are so expensive.
note: also if anyone has a protein skimmer that they would be willing to let go of for free or very cheap. (higher-ups if I shouldn't post that here just delete it or let me know and I will edit or delete it)
