Question: Aerator / Air Stone

[Kipper]

I have been looking at getting an air stone for my 20 gallon tank. I was wondering if anyone can recommend one they have had a good experience with.

Also, are there any suggestions about the size of the air stone? I am planning on getting a small one to put in the corner, but I was curious if too many bubbles is a bad thing in case I decided to get a larger one. I will definitely make sure it isn't bite-sized!

Air stones are pretty generic. I've never tried the wooden ones.

Too many bubbles shouldn't be a problem unless they cause noticeable turbulence in the water. They do make some air pumps that are adjustable.
