So I'll start by saying that after trying almost a dozen nano-skimmers, most of them aren't very effective. But this little guy is doing a wonderful job. The Skimmate is a little wet, but more gets into the cup every day. I've been working on my nuvo 20 for about a month, everything is fine. Tight, I mean tight on the nuvo 20 tablet, but it works. I found that only 4 of the 11 Nano Skimmers I tried worked enough to make a difference. This is the top 2 if not the best. Let it run at full capacity for a few days, then adjust the water level to the bottom of the cup and you're golden.
