Hi Hunter, I put a couple of these in my shrimp tank. I bought from eBay which has a guy in the Midwest that sells like 4 double sponges for ~$10. That store also has air pumps that you buy. I'm sure there are quieter air pumps out there, but it was convenient to get 4 sponges, air pump, air tube and check valves all in one place. I think it was $25 total.
