Octo 2000HOB Intake Elbow
SKU: ROP-BH2000-INEB
- Genuine OEM Direct Replacement: Authentic factory-spec water intake elbow engineered specifically for the large-format Reef Octopus Classic 2000HOB (BH-2000) hang-on back protein skimmer.
- High-Volume Metric Sizing: Custom-profiled to integrate flawlessly with the native 2000HOB intake configuration, allowing optimal siphon stability.
- High-Impact Molded Polymer: Constructed from heavy-duty, marine-grade PVC composite that easily resists physical cracking, deep scoring, and salt creep.
- Seamless Friction-Lock Connections: Features precise slide-on slip sockets that firmly interlock with your native siphon pipes and surface skimmer attachments.
- 90-Degree Flow Optimization: Calibrated geometry routes high-capacity water volumes cleanly over your aquarium rim without kinking or stressing the external pump.
- Toolless Slide-On Installation: Drops directly into your existing plumbing assembly without the need for messy plastic adhesives, threads, or hardware modifications.

Reef Octopus Classic 2000HOB Replacement Intake Elbow (ROP-BH2000-INEB)
The Reef Octopus Classic 2000HOB Intake Elbow (SKU: ROP-BH2000-INEB) is a genuine factory-direct OEM replacement plumbing fitting distributed by CoralVue to preserve the smooth siphon mechanics of your high-turnover hang-on back filtration loop. On a heavy-duty external HOB protein skimmer like the Classic 2000HOB, the intake plumbing has to safely bridge the structural gap between the submerged aquarium display and the powerful Aquatrance 2000s pump mounted behind the glass. Because this elbow handles the immediate raw influx of water being drawn into a high-capacity system, it experiences non-stop mechanical tension. Over years of equipment service, pulling the pipe assembly apart to clear out trapped snails or algae can cause the friction joints to stretch out, and accidental knocks during aquarium cleaning can crack the molding, creating micro-air leaks that break the siphon vacuum.
Replacing a fractured or worn fitting with this authentic drop-in component fully restores your system's structural integrity. The inner diameter is custom-profiled to eliminate fluid friction restrictions, allowing your external pump to draw its full rated water volume for optimal air-to-water mixing. By restoring an airtight link across your tank frame, this elbow ensures your large-body skimmer starts up cleanly without loud water surging, sputtering cycles, or accidental overflows.
Key Features
True Factory Sizing Profile: Sized strictly to meet original factory specifications to fit the Classic 2000HOB (BH-2000) intake grid.
Smooth Internal Radius: The internal 90-degree curve is smooth-finished to prevent raw organic waste, fish food, or floating debris from collecting in the bend.
Chemically Inert Formulation: Fabricated entirely from stable, non-leaching marine plastics that will not alter water parameters or cause skimmer pumps to boil.
Secure Slip Connection: Engineered to maintain tight metric tolerances with standard native plumbing lines for a tight, toolless friction fit.
Verified Hardware Compatibility
Reef Octopus Classic HOB Series: Sized explicitly for the oversized Classic 2000HOB (commonly referred to as the BH-2000) hang-on back external skimmer line.
(Note: This fitting features specific inner diameter thresholds calibrated exclusively for the high-flow 2000HOB framework. If you utilize smaller skimmer models like the Classic 100HOB or 1000HOB, please source their alternative matching intake elbow sizes to ensure a proper interlocking fit).

- Turn off your protein skimmer's Aquatrance pump to stop all active water transit through the suction lines.
- Carefully lift the intake assembly pipes away from the aquarium frame and lay them on a clear workspace.
- Disengage the damaged or calcified elbow from the intake tubes by twisting gently to break any dried salt crust.
- Thoroughly clean the ends of your existing rigid extension tubes with a soft towel to remove any built-up coralline algae or debris.
- Push your new ROP-BH2000-INEB replacement elbow firmly onto the intake lines until the slip sockets seat completely flush.
- Re-hang the intake pipes over your tank rim, manually fill the skimmer column with water to prime the siphon, and turn the pump back on.
Pro Tips:
- Never Use PVC Glue or Cement for Installation. While standard household plumbing repairs rely on permanent solvent welding, you should never apply PVC cement, superglue, or plumbing epoxies to attach this intake elbow to your skimmer components. This connection is designed as a clean, unglued friction fit so you can easily pull the intake assembly apart for seasonal cleaning. Gluing the elbow permanently makes it impossible to remove the pipes or clear out hidden obstructions down the road.
- Keep an Eye on the Slip Joint O-Rings. When pushing the new intake elbow onto the skimmer's connection tubes, double-check the condition of the sealing rubber O-rings located inside or around the joints. If these O-rings are pinched, dry-rotted, or out of alignment, the pump will suck micro-bubbles of air directly into the intake line. This air leak ruins the siphon vacuum and can cause the skimmer to constantly lose its prime or bubble erratically.
- Clear Away Calcareous Build-Up with Citric Acid Soaks. Because raw, unskimmed water passes through this elbow first, it is highly prone to catching small crawling pests, fine sand grains, and accumulating pink coralline algae crusts. Never shove metal screwdrivers or wire bottle brushes into the bend to clear out a block, as this can deeply scratch the inner walls. Instead, drop the elbow into a warm bath of water mixed with pure citric acid powder for 20 minutes to safely dissolve away hard scale.
