Can I use an air pump with a power filter, and if so, how should I set it up?

Gunnie

Yes you can. The air pump does not connect to the power filter. Simply get you some air hose, connect one end of the hose to the air pump, and the other end to a sponge filter or air stone.

What is an airstone, and where does it go?

Gunnie

An airstone is what you connect to your air hose to control the bubbles. You can get airstones for tiny bubbles, big bubbles, or even a buttle wall. You can also connect your hose to decorations like treasure chests which use the bubbles as part of the decoration, and make them move.

I think that underwater bubble river would be really cool. If someone ever gets one you have to share pictures of it with us. 8)
