Flow for a 2g cookie jar?

[ps2cho]

For fun I set up a 2g cookie jar. Is there any options for flow outside of an air pump? I just want to keep noise down to a minimum and the air bubbles are really loud.

Would adding an air stone work better to keep noise down? What are you guys using?

well, if you have a lid on it, air bubbles would likely be muffled.

 

I'm starting up a 2.5 gallon in a bit with a long term plan to create a 5 gallon bucket sump for it to make for easier water changes and balance my variables as I want to keep a crab in it. if you go into the DIY section, you'll see the 5 gal bucket sump project. it's engenius! 

 

anyhow, if you were to engage a bucket sump...be it 5 gal or smaller, you would use a submersible water pump, which would definitely be muffled. just have to find one that can operate at the low flow volume required and has enough head.
