Hi all.

Is it necessary for the water surface to be broken in order for oxygenation to occur? Ie, via bubbles, a power filter's water return, etc. Or is water circulation enough to oxygenate the water? Cos I currently have an internal power filter in an unplanted 10gal and it's keeping up a decent water flow, but being a submerged filter, the actual surface of the water isn't being broken.

Thanks.

Hey,
It is not necessary to break the surface for gas transfer. As long as you have good circulation there should be plenty of oxygen going in. Of course in some situations you might need extra oxygenation, for example in a heavily stocked tank, during a heatwave or when using certain medications. In these cases an airpump and airstone will do the trick. Smile
