Surface Agitation/Gas Exchange
I've just swapped out my two Koralia 1 powerheads for a shiny new Vortech MP10 ES. I have a question about surface agitation.
When I had the Koralias, I had them pointed at eachother with upward angles in order to break the surface tension. I'm currently running my vortech on "reef crest" mode and have noticed that there's lots of movement within the tank water but substantially less ripples on the surface of the water.
I'm running a 15G nano tank that has no overflow or sump. The Vortech is the only flow. Should I be worried about gas exchange?
