Surface Agitation/Gas Exchange

Well, I've spent a lot of the night between writing my paper (which was often!) watching the tank and when the Reef crest mode increases to full power (I have it set to about 40%) it creates a lot of surface ripples. So that and the skimmer should be fine. I'll keep watch over my fish the next few days and make sure they're good, but I'm not worried about it anymore. Thanks for the replies all!

for a 15 gallon I'd think the vortech on full would turn that thing to chowder.
but I got a MP20 on a 40 breeder and there's some good current from 3 inches below the water line so I'd think you're good.

It's set to 40%.

I love the pulse mode and find it as the best option....it cleans up your tank, agitate the water surfers, bring food to corals and wash them from mucus and stuff...
