The NAC QQ Nano Hang skimmer from Bubble Magus is an adorable little fractionator for the masses. The Hang on moniker is a little deceptive because instead of hanging on the outside of your tank, this little tyke likes to hang out in your tank, in plain sight for all your corals and fish to see it’s undercarriage. Like other Bubble Magus cylinders, it has a pump, it has a cylinder and it has blue fittings that do absolutely nothing to disguise themselves when running on the inside of your tank. Unless the Nano NAC QQ is meant to hang on the inside of your sump, we can’t imagine this skimmer beging highly desirable with such an awesome option like the Slim Skim Nano from Hydor. Unless it is really affordable, like stupid cheap.
