topic as old as my neighbour
Do You use airstone in Your reef tank?
Will skimmer do good enough job with oxygenating water?

...and of you go guys....

No need for an airstone.

Your better off just pointing a powerhead at the surface, or getting enough flow for surface agitiation.

i dont. between the skimmer, water falling through the drain into the sump, and surface agitation in the display, i think im ok on gas exchange.
