I have had this running in my Nuvo 20 AIO for a few months. First, I don't feel that this skimmer is that great. Never see anything in the cup, even when it is set low. But my biggest gripe is that it filled the tank with micro bubbles. I have it in the second slot from the right so it dumps into the return area. it won't fit into either of the end compartments. I turned it off today as one of my new wrasses was getting irritated by the bubbles. Probably will do without. Anyone get one of these to work well?
