It may not be the smallest ever, but it's the smallest I've personally seen. On my JBJ 12g nano, I'm running that Sapphire skimmer. It's always been a lot noisier than I thought it should be, and the pump it comes with has been extremely inconsistent, so I replaced the pump. I'm now running a MicroJet 320, and I mesh modded it! Sure, this seems a little silly, but I thought I'd give it a shot, anyway.
The pump is so small, I could only put a single layer of Enkamat on it. The impeller had three blades on it, and I cut those way down, to about 1/4 their original size. I left that little on there, so I'd have something to attach the mesh to so it would spin. The scale of the project is so small, I wasn't able to use the standard fishing string ties (and especially not zip ties) to attach the mesh. I tried super glue gel, but I made a bit of a mess of the whole thing with that. You can still see the residue on the inside of the impeller housing on the pump in the photos below. In the end, I used some aquarium silicone I had sitting around. Just a dab on the end of the impeller has held the Enkamat mesh without issue. I also had to drill a hole in the pump body for the air inlet. I took a look at my existing pump, and just matched it. It really wasn't anything fancy, at all.
In the end, the actual mesh ended up being a single layer, about the size of a nickel. It's only been running less than an hour, so I can't say much for any increase in performance, but it's definitely a LOT quieter, and the bubbles are undoubtedly much finer. If I pull off the collection cup, the bubbles almost look like smoke at the top of the skimmer body.
