[Sk8r]

SOmething many people don't know about their skimmer: it is one major source of oxygenation for the tank. The bigger the better if you have oxy-hungry fish.

And microbubbles. They're always worst when a skimmer is new. You'll notice that bubble-deflator is a nice attachment on that nice skimmer.

But I have what I think is a rather clever way of getting rid of them, too. I send my skimmer outflow back to the first chamber of my sump, forcing the microbubbles to go through the fuge and a huge ball of cheatomorpha algae. No bubbles make it to the other side, where the next chamber is the heater and then return pump and skimmer pump.
