Wave box causing micro bubbles.

[Reefrookie2006]

I recently noticed a microbubble problem in my tank. I found the wave box causing the bubbles when blowing the water out, even I adjust it on the center point. I'm also using 4 section cups to hang the wave box on the corner of the tank. If you have any experience with this please help me.

I would get at least one magnet holder, the suction cups sound really precarious to me and if they go the box will float up and blow the water out of your tank, the result could be disastrous. How big is your tank? It sounds like you have a long frequency and the box is emptying, it may not be submerged deep enough or you may need to turn the screen of the pump solid side up.
