Euro Reef

[Jaws]

There's lots in the tank. I can't get a thick steady overflow of bubbles. When it does work, it's mostly water collecting in the cup rather than skimmate. It's almost like a hot tub. There seems to be so much flow going through the bubble chamber that the bubbles won't collect at the top. The ones that do just burst and all appear to look very wet. If I close the gate valve enough to push these bubbles into the collection cup, I just end up with mostly water. I'm starting to get frustrated now because i'm starting to get a cyano buildup in the tank.
