another airstone question

Hello, I have a 10 gal tank with a bubble wall at the back. Not particularly strong though. I like water movement and would like to place a small airstone elswhere in the tank, is that ok to do? Is there any such thing as 'too much'? The fish love the bubbles and I like the look.
I guess I would need a separate air pump, which is no prob.
Thanks......just bought two littles ottos today, they seem fine and so far haven't gone into hiding.

 

I don't think another air stone would cause any harm.

 

It will be fine as long as none of your fish are struggling or fighting the water movement.

Depending on how good your existing air pump is and how big your airstones are you could probably get a gang valve and run both air stones off the same pump.

 

Thanks, a Gang Valve, will try for that today.
