Saltwater tank refugium question!!?

ok i have a salt water refugium set up. It is an actuall refugium not like a 10 gallon tank or anything. My only question is this, should i have like an air stone in it as it does not seem like there is allot if any movement of water though it.
The water is filling up and leaving the other side but it just looks like for the most part it is stagnant and just sitting there. Would an air stone be ok and should i do that?
Answers:
The amount of water leaving your tank is the same amount being returned by your return pump.
Therefore if you have 400gal per hour going into one side, you have 400gal per hour coming out of the other side of your sump or fuge (or sump fuge mix)
A refugium is designed to spread that current out over a large space so it will pass through everything you have in it at a slower pace (Not blasting on one rock or blowing your plants(micro algae) all over the place.
NO Definitely DO NOT put an airstone in there, the bubbles will stick to everything in there and end up in your tank.
no, dont put an airstone in it. that is how the flow in a refugium is supposed to be.
