water flow to fuge

[escape2thewater]

Does it matter if the water surface is aggitated in a fuge? I had mine set up so it drained above the surface then switched it to a underwater drain. Now it no longer has any movement on the surface. Is this ok or should I put it back?
Thanks,
KH

I've always been under the impression that surface movement is crucial for oxygen x-fer.... I could be wrong however.
If it was me I would switch it back.... but then again I don't have a fuge yet so I can not say from personal experience.
Cheers!

Personally, I like the surface water in the sump and fuge to be aggressively agitated just for extra gas exchange.

Thanks, I guess i'll put it back how it was. I figured it would be better for it with aggitation but wanted some more input.
Thanks again,
