Innovative. Powerful. Attractive.
The very eSsence of Filtration

The Reef Octopus eSsence S-130 Protein Skimmer was designed for the modern day aquarist in mind. This remarkably compact in-sump protein skimmer is capable of skimming aquariums up to 160 gallons where sump space may be limited.

Efficient Performance

At the core of the skimmer we have the reliable and extremely efficient Reef Octopus Aquatrance 1800s pinwheel pump. Reef Octopus was the first protein skimmer manufacturer in the world that designs and produces our own skimmer pumps. Aquatrance skimmer pumps have been specifically engineered to enhance and increase the efficiency of our protein skimmers.

Ease of Use

Removal of the collection cup could not be more simple with the Twist & Lift connection which doubles as a detachable air silencer. A calibrated 16 step water level adjustment dial takes the second-guessing on your skimmer`s setting.

Simple to Maintain

Constructed of high-quality molded parts that completely disassembled for easy cleaning. No hard to manage screws here, the quick release tabs make access to the inner body a breeze.

Quiet Operation

The skimmers unique 360 submerged output disperses water back into the sump without turbulence providing a quiet splash-free discharge. The detachable silencer collar is 12% more quiet than standard silencers.

Internal model designed for in-sump use only. No feed pump required, skimmer draws water directly from sump.

Pros: NONE imo


I understand about break-in periods and other chemicals in the column that cause issues. But I had this unit running upwards of 4 weeks and this unit constantly boiled over out of no where and not just filing the cup but blowing the lid off the cup for up to and beyond 12 + hours. I lowered water level in the sump to below recommended levels and had valve fully opened and that did nothing !! I finally called Marine Depot and they referred me to Coralvue, They are blaming me and talking to me like I'm clueless. Also saying that there is nothing wrong with this skimmer - buyer beware.
