Octo Elite 150INT (VarioS 2S) Air Venturi
SKU: ROP-VNTR-ELITE150INT
- Genuine OEM Direct Replacement: Authentic factory-spec air-water induction nozzle designed exclusively for the out-of-body pump configuration on Elite 150INT Super Cone skimmers.
- Calibrated Vacuum Venturi Throat: Engineered with a precision internal constriction pathway that maximizes vacuum pull to achieve the pump's 900 L/H factory air-draw spec.
- Ozone-Safe Air Barb Terminal: Features an integrated rigid barb nipple built to fit securely onto standard flexible air silencer hosing and ozone injection networks.
- Streamlined Bubble Fractionating: Smooth internal geometry splits incoming fluid streams into tight clouds of microbubbles without restricting core pump volume.
- Saltwater-Inert Material Base: Molded out of a robust, heavy-wall polymer blend that completely resists chemical breakdown, cracking, or organic sludging.
- Toolless Push-Fit Calibration: Slides seamlessly into the native intake tracking of your VarioS-2S pump volute faceplate, making routine seasonal cleanings effortless.

Reef Octopus Elite 150INT Replacement Air Venturi (ROP-DC-VNTR-ELITE150INT)
The Reef Octopus Elite 150INT Air Venturi (SKU: ROP-DC-VNTR-ELITE150INT) is an authentic factory-spec replacement gas-induction nozzle distributed by CoralVue to restore and preserve the high-efficiency waste stripping dynamics of your protein skimmer. In the traditional internal sump layout of the Elite 150INT, where the pump sits open alongside the wine-glass super cone body, the VarioS-2S pinwheel pump relies entirely on the negative vacuum pressure generated by this specialized venturi nozzle to draw fresh air down from the silencer canister. As water rushes through the restricted inner throat of the adapter, it accelerates exponentially, creating a continuous low-pressure void that aggressively pulls in air and directs it into the spinning needlewheel to be chopped into organic-binding microbubbles.
Over years of nonstop operational cycles inside active sumps, this intake point is highly prone to calcification choke points. The continuous evaporation of water right at the raw air injection boundary causes calcium carbonate scale and salt creep to crust over the inner orifice line. If left unmanaged, or if the plastic barb is accidentally snapped during a deep maintenance washout, your skimmer’s performance will tank. A compromised venturi bleeds critical air volume, resulting in a low, watery foam head, excessive microbubble spitting into your display tank, and an overall loss of chemical filtration capacity. Installing a fresh original factory nozzle immediately re-calibrates original internal tolerances, ensuring a tight seal for flawless waste collection.
Key Features
True Elite 150INT Optimization: Sized and angled specifically to accommodate the out-of-body plumbing path native to the traditional 150INT super cone footprint.
Anti-Corrosive Polymer Durability: Built using heavy-wall injection-molded plastics that endure aggressive citric acid descaling baths and continuous exposure to pure ozone gas.
Airtight Internal Seal Mechanics: Machined slip collar lines seat snugly against the pump housing face, eliminating localized pressure loss or unsafe microbubble weeping.
Optimized Air-Water Induction Path: Smooth inner tracking guarantees that your VarioS-2S motor reaches its full 900 L/H maximum factory air-draw specification.
Verified Hardware Compatibility
Reef Octopus Skimmer Infrastructure: Tailored exclusively as the matching replacement intake venturi adapter for the Reef Octopus Elite 150INT Protein Skimmer (Traditional Internal Sump Variant powered by the VarioS-2S Controllable Skimmer Pump).

Technical Specs:
Official Manufacturing Title: Reef Octopus Air Venturi for Elite 150INT
SKU / Factory Part Identifier: ROP-DC-VNTR-ELITE150INT
Profile Configuration: Straight-Neck Slip Nozzle with Friction-Fit Air Barb Terminal
Material Composition: Saltwater-Safe High-Density Injection-Molded Matte Polymer
Primary Function: Air/Water Volumetric Proportioning & Fluid Acceleration Failsafe
- Turn off your skimmer's pump controller and pull the main 24V power brick out of the wall to eliminate live electricity before servicing your gear.
- Disconnect your flexible silicone air intake line from the old venturi barb nipple, and slide the VarioS-2S pump completely clear of the skimmer body base track.
- Pull the old, calcified, or damaged venturi adapter straight out of the front intake neck of the pump volute cover. (If it is stuck due to salt buildup, twist gently as you pull).
- Take your new ROP-DC-VNTR-ELITE150INT replacement venturi, check that the slip nozzle faces are free of debris, and push it straight into the intake neck of the volute until it sits flush.
- Slide the pump back into the skimmer housing tracking, snap your flexible air line firmly onto the raised plastic barb nipple, and lower the unit into your sump.
- Plug your power converter back into the wall outlet, let the soft-start controller cycle complete, and check that a dense mist of bubbles instantly fills the reaction chamber.
Pro Tips:
- Clean the Air Injection Orifice with a Toothpick Monthly. Because this venturi operates right at the point where raw air meets high-velocity saltwater, it is the number one hotspot in your filtration loop for salt creep crust and hard calcium scaling. If you notice your skimmer foam dropping or the water line inside the body rising erratically, check this nozzle first. Use a wood toothpick or a small plastic brush to clear out the inner injection channel to restore full air volume without scratching the internal tracks.
- Never Use Drills or Metal Tools to Force Open a Clogged Intake. If your venturi nozzle becomes heavily clogged with rock-hard calcium scale, never use drill bits, steel drill strings, or sharp metal knives to gouge the blockage loose. This venturi depends on a highly sensitive, micro-engineered internal curvature to generate its vacuum draw. Scratching or widening the inner channel with metal tools will ruin the hydrodynamics of the plastic, permanently destroying its performance. Soak the part in a citric acid bath to dissolve blockages safely.
- Utilize Warm RO/DI Water Flushes to Melt Salt Creep Instantly. To extend the time between deep equipment cleanings, perform a quick venturi flush every two weeks. Disconnect the flexible air hose from your silencer canister and hold the open end of the tube up to a small cup filled with warm fresh RO/DI water while the skimmer pump is running. The VarioS-2S pump will draw the warm fresh water straight through the venturi barb, instantly dissolving soft salt creep rings before they can harden into a calcified restriction.
