I started my list with the protein skimmers mentioned in BRS's "Will It Fit?" video about the JBJ Nanocube 24. That one did not fit all the way in the middle rear compartment, but if it's small enough for consideration, that's nano enough for me!I don't know if I would consider it a nano skimmer though. It's rated for up to 70 gallons.
I removed the baffle/divider between chamber 2 and the return in my jbj 24 cube and was able to squeeze in an aquamaxx ws-1. I run it about six hours once or twice a week depending on how heavy I feed and water change frequencyI started my list with the protein skimmers mentioned in BRS's "Will It Fit?" video about the JBJ Nanocube 24.

I have one of these now and it's an excellent skimmer, producing about 1/4c of light skimmate a night on an IM 30L. It's also much quieter than the other small skimmers I have tried.I had the aquamaxx hob-1. It was a great skimmer. Pretty quiet, good skimate production.
