 AquaC Urchin Pro Protein Skimmer

 - Rated for tanks between 50-120 gallons

 - Slim design works in tight spaces

 - Available without pump, or with either a Mag Drive 3 or Rio 1400 pump

The Urchin Pro is the sump version of the Remora Pro. These two skimmers share the same internal structure and are identical in terms of performance. The Urchin Pro can be purchased with a Rio 1400 or a Mag Drive 3, the latter resulting in the best performance.

 - 22" tall x 7-1/2" wide x 3-1/4" deep

 - 8-1/4" x 7-1/2" footprint (pump included)

 - Minimum vertical clearance is 26-1/2 "

 - Water level exit height is 15"

 - Includes Rio 1400 or Mag Drive 3 pump

 - Rated for tanks up to 120 gallons

 - Includes nylon cleaning brush

 - Collection cup drain is optional

 - EPDM o-ring for collection cup adjustment


The Urchin Pro is built from translucent gray acrylic to inhibit the growth of algae and marine organisms.

The skimmer can be ordered with a collection drain fitting (optional).

The pump is attached to the skimmer via a section of flexible hose. The pump can be moved into any position you choose.

The collection cup is removed from the skimmer by pulling it up and out of the body. Please check that you have the required 26-1/2" of vertical clearance under you stand if you are considering the Urchin Pro.


The revolutionary AquaC protein skimmers do not use venturis, downdraft tubes, or air pumps; they employ the patented "Spray Injection System." This innovation allows the protein skimmer to efficiently draw in much more air than any other of the top protein skimmers. This coupled with the superiorly designed compact reaction chamber yields results that will literally blow the waste out of your water.

How does Spray Injection Work?

In 1998, Jason Kim (owner and founder of AquaC) developed a patented process of protein skimming which has come to be known as Spray Injection. Unlike previous forms of skimming, our spray injection method enables huge amounts of air and water to be processed with a relatively small pump. Although it is a simple process, there is still some confusion as to how the spray injector works.

Imagine that you're washing your car – you've got a bucket full of soapy water and a garden hose with a fast-moving stream of water. By placing your thumb over the end of the hose, you can disrupt the stream into a turbulent, high –pressure spray. Now direct that spray down into the bucket of water, and you'll generate a massive amount of bubbles and air flow. That is exactly how our spray injector works.

The skimmer body acts as a water reservoir – the bucket in the example above. Water is pumped through the spray injector, which has a special nozzle that fans the water out into a pressurized spray. This spray shoots into the skimmer body, generating millions of tiny air bubbles. As the bubbles are formed, more air is sucked into the skimmer as a result of the local drop in pressure and the process continues.

Most other forms of protein skimming rely on special valves or media to generate the air flow, and these parts quickly become clogged with salt, dust, or even mineral deposits. The AquaC spray injector is a relatively large nozzle that resists clogging, and when combined with a pump prefilter, can be considered maintenance free.
