Reef Octopus eSsence S-130 Protein Skimmer has been designed from the ground up to create a super silent, space-saving skimmer. The biggest change that you will notice is the quick connect tabs that hold the body to the base plate. Within just a couple seconds you can disconnect the body from the base for cleaning, or service the pump. Other innovative features include an integrated silencer into the neck of the skimmer. The Silencer is auto-draining and the large chamber keeps any noise from becoming audible.

Tuning the S-130 is easier than ever with the 16 step click dial that lets you perfectly adjust your skimmers internal water level. With traditional gate valves or wedge pipes, you can almost never recreate the same setting if the valve is ever bumped or turned. The S-130 click dial easily lets you retune your skimmer in the event that something changes. One of the biggest change to the eSsence S-130 skimmer is its fully submerged discharge pipe. The unique 360-degree pipe has special cuts to keep the water exiting the skimmer from splashing and making any noise.
