Octo VarioS 10 Intake Strainer
SKU: ROP-VAR10-STNR
- Genuine OEM Direct Replacement: Authentic factory-spec protective suction strainer basket designed specifically for the flagship Reef Octopus VarioS-10 controllable DC pump.
- Oversized 50mm Threaded Base: Engineered to screw directly onto the native 1.5-inch male threaded input socket of the pump's high-volume volute housing.
- High-Surface Area Screen Grid: Features a grid matrix that maximizes fluid induction while creating a secure physical barrier against macro-debris.
- Vital Livestock & Hardware Defense: Actively prevents wandering marine snails, macroalgae clumps, loose substrate, and curious fish from entering the impeller bay.
- Premium Molded Polymer: Fabricated from robust, saltwater-inert plastics that resist brittleness, environmental cracking, and ozone degradation.

Reef Octopus VarioS-10 Replacement Intake Strainer (ROP-VAR10-STNR)
The Reef Octopus VarioS-10 Intake Strainer (SKU: ROP-VAR10-STNR) is an authentic factory-spec replacement protective screen distributed by CoralVue to preserve the operational safety and interior hardware integrity of your high-volume circulation loop. When running the industrial-class VarioS-10 pump in a submersible configuration inside a sump or open filtration reservoir, its massive suction capacity generates a powerful directional vacuum draw. Without a dedicated structural barrier over the intake mouth, this localized suction stream can easily pull floating macroalgae, loose filter pads, substrate pebbles, or wandering invertebrates directly into the high-velocity spinning core of the motor block.
If a hard object like a turbo snail shell or a loose fragment of rock bypasses an open intake and strikes the internal impeller, it can instantly snap the specialized ceramic rotor shaft or lock the motor assembly under high resistance. While the smart VarioS controller features electronic auto-shutoff failsafes to detect current surges, the physical impact alone can permanently gouge the internal volute chamber walls or strip the magnetic block, resulting in a costly and preventable system failure. Installing this genuine OEM threaded basket over the intake nozzle creates a secure physical boundary ring. The optimized grid structure safely diffuses the aggressive intake vacuum across a larger surface area, preventing structural flow restriction and cavitation while keeping your high-pressure pump perfectly insulated from internal damage.
Key Features
True Factory Sizing Tolerances: Molded with high-precision threads to drop cleanly onto the oversized 50mm (1.5-inch) input tracks of the VarioS-10 pump face.
Hydrodynamically Slotted Matrix: Built with elongated perimeter slots calculated to supply an un-constricted, high-volume fluid path that meets the pump's 4,220 GPH operational demands.
Reef-Safe Structural Material: Constructed from dense, chemical-inert plastics that will never pit, leach heavy plasticizers, or degrade under direct saltwater submersion.
Deep-Thread Structural Collar: Heavy-duty base ring provides excellent cross-thread resistance and stays firmly anchored under high-vibration pump currents.
Verified Hardware Compatibility
Reef Octopus VarioS Pump Ecosystems: Tailored exclusively as the correct matching suction pre-filter for the Reef Octopus VarioS-10 Controllable Circulation Pump.
(Note: This strainer is engineered strictly for the native 50mm threaded volute housing of the flagship VarioS-10 line. Smaller pump families, such as the VarioS 2, 4, 6, or 8 series, utilize narrower intake metrics and require their respective model-specific replacement strainers).

- Power down your VarioS-10 pump controller and disconnect the main 36V power grid transformer from the wall to halt all internal impeller rotation.
- If your pump is installed inside a crowded sump bay, clear away neighboring equipment to give your hands free access to the front volute cover.
- Unscrew the old, damaged, or algae-clogged strainer counter-clockwise off the front-facing 50mm suction nozzle of the pump housing.
- Wipe off the male threads of the pump volute cover with a soft cloth to clear away any trapped debris, slime, or gritty salt creep.
- Take your new ROP-VAR10-STNR replacement strainer, align it straight against the intake nozzle, and thread it clockwise by hand.
- Spin the strainer down firmly until the shoulder collar sits flush against the volute face. Do not overtighten, submerge the pump, and restore power.
- Only Use This Screen in Submerged (Wet) Applications. This plastic intake strainer is strictly intended for open submersible installations where the VarioS-10 pump sits directly underwater in a sump or pond bay. If you are plumbing your VarioS-10 pump inline as a dry, external return unit outside of your glass sump, you must remove this strainer entirely and replace it with a hard-piped 50mm rigid metric PVC union connection to prevent massive external flooding.
- Clean the Strainer Grid Monthly to Stop Cavitation. Because this screen sits right at the primary suction point of a high-power 200W motor block, it will naturally act as a magnet for floating organic debris, loose macroalgae strands (like Chaetomorpha), and soft bacterial films. If you allow these materials to build up and coat the grid slots for months, the restricted water path will force the pump to starve for water. This restriction triggers localized cavitation, loud rattling noises, and unsafe heat buildup inside the ceramic bearing bay. Brush the screen clean during your monthly sump maintenance.
- Always Hand-Tighten Only — Avoid Metal Pliers. When screwing your replacement strainer onto the premium front volute cover of the pump, never use channel locks, vice-grips, or metal wrenches to crank it down tight. The strainer base is made of molded polymer plastic; using heavy mechanical tools will easily split the threaded collar ring or cross-thread the fine plastic channels on your expensive pump volute. Gentle fingertip pressure is all that is required to seat this safety screen securely.
