Selling Terms Of Service
  1. YES I have read the terms and agree to them
Rated up to 175 gallons in a design compact enough to be placed on a small or medium-size saltwater aquarium. Brand new is $350. The skimmer is in great condition and has only been used for about a year. I love this skimmer, but I added a sump to my tank and don't need the HOB model anymore. Some of the ribs on the intake screen are missing or snapped, but it doesn't affect the skimming performance - see pics.

For sale $120. Prefer to sell locally (Durham, NC) but will ship at the buyer's expense.

Here are the specs from BRS:

From the product description:


  • Modified and upgraded Italian Sicce needle-wheel pump produces optimum bubble size for high-efficiency protein skimming
  • Cone body extends through the collection cup to easy bubble transition and maximize skimmer efficiency
  • Efficient, durable and reliable
  • Simple to set up and operate
  • Cell-cast acrylic construction
  • ShockMaxx rubber feet isolate noise and reduce vibration
  • New outlet design minimizes footprint, reduces skimmer height and allows for fine-tuning
  • Exclusive collection cup design with a handle that allows you to easy hold and transport the collection cup for cleaning
