I have this skimmer in the back of a new Innovative Marine Nuvo Fusion 20 gallon. It fits perfect. I've had several different skimmers in the past, so I have some knowledge of their operation and weak points.
At this early stage (less than a week) the skimmer is emitting lots of micro-bubbles into the main tank. Supposedly it will go away within a week or so.
I have about 10 pounds of cycled rock in the tank for a small bio-load. It seems the water level in the main skimmer body fluctuates without any changes to the skimmers level, outlet tube or the air adjustment knob. The outlet tube is wide open. I adjust the level so it's about 1/4 - 3/8 inch from the bottom of the cup, just to be safe. Then within a few hours I'll look at it and the level has risen into the upper tube, or overflowed the cup completely. When the cup overflows, it drains back into the tank. Not good but better than on the floor!
The design seems sound, but not sure if the fluctuating level situation came be adjusted out so there's a large degree of safety. As for sound level, it's very quiet.
It would be appreciated and useful if the cup had a drain port, fitting and silicone hose.
I'll report back in a month or so, J
