The Reef Glass Nano Skimmer is a high quality air pump driven protein skimmer specially designed for nano reef aquariums. It is based on the traditional air-driven method using limewood airstone with many improvements. The unique design is very simple, yet elegant and functional.


  • Skimmer body made of high quality Pyrex glass. The unique design eliminates the need for a side drain, making it simpler and more robust. Made, cut and fire polished in the USA.
  • Polycarbonate mount that fits most rimless and rimmed tanks. The design allows for air and drain tubing to be organized and incorporates options for back and front screws, adding versatility. Also, made in the USA.
  • Small size, ideal for nano reef aquariums up to 30 gallons.
  • Straight shape allows for easy replacement of the limewood airstone from the top of the skimmer without removing it from the mount.
  • Includes limewood airstone, two-hole rubber stopper, tubing and all necessary connectors. All you need is an air pump that can deliver around 1 L/min of air and a waste container (good opportunity to recycle a plastic bottle).
  • Silent operation.
  • Does not add heat to your nano reef aquarium, unlike Venturi and needle wheel pump skimmers.
  • Improves water oxygenation.
  • Dimensions: 1.25"x 1.25"x 11.5"
  • Fits tanks with thickness up to 1"


Note: A sufficient air pump is required and sold separately. We recommend the Eheim Quiet Air 100 or similiar size (~1 L/min) air pump to deliver air into the protein skimmer.

Product Questions

what air pump is a good match here? I was thinking eheim 400 would be ok.
Question by: Drew Young on Feb 14, 2023, 9:39 AM
We recommend an air pump that does around 1L/min.

The Quiet Air Pump 100 would work great for this skimmer

Will this aerate the water as well as any other skimmer? Looking to use it in a saltwater conversion of a Fluval Flex 15 which cannot have a lot of surface agitation or high flow due to livestock requirements.
Question by: Chris on Feb 13, 2023, 12:18 AM
Yes! This will create a substantial amount of bubbles which will help aerate the water. it will aerate just as much as other similarly sized skimmers.
