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.

Product Questions

Ozone safe?
Question by: Christopher Stewart on Feb 1, 2023, 5:23 PM
Thanks for the question! BRS does not recommend the use of skimmers as ozone reactors. This is one I would not suggest using regardless due to its venturi style
Answer by: James Johnson (BRS Staff) on Feb 16, 2023, 3:29 PM
How much liquid does the cup hold? Thank you
Question by: Lawrence Steven Block on Apr 10, 2022, 9:07 AM
The collection cup holds approximately four cups.

Hi quick question, will the ESSENCE S-130 fit in a Trigger EMERALD SUMP 26 ?
Question by: Douglas Sanchez on Jan 9, 2018, 10:16 AM
Thanks for contacting BRS!
This skimmer appears to be a hair too big. The skimmer section of the sump is 8.25? x 10? and the skimmer footprint is 8.3” x 6.9”. Have a great day!
