Reef Octopus Classic 2000HOB Replacement Collection Cup Lid (ROP-CCLID-BH2000)
The Reef Octopus Classic 2000HOB Collection Cup Lid (SKU: ROP-CCLID-BH2000) is an authentic factory-spec replacement top cover distributed by CoralVue to maintain environmental safety and pressure control across your hang-on back filtration system. On an active hang-on back protein skimmer like the Classic 2000HOB, the collection cup lid performs a crucial double-duty role. It acts as a physical boundary that deflects hyper-active microbubbles and popping saltwater spray back down into the reservoir, while providing precise top-end ventilation holes to ensure the skimmer's internal air volume can vent cleanly without causing a performance-stifling backpressure bottleneck.
Because the collection cup needs to be removed and dumped frequently, the lid is constantly being handled. Over years of aquarium operation, lids can get dropped onto hard utility floors during washing, stepped on, or lost entirely during deep equipment cleanings. Running a high-performance external skimmer without its native top cover can quickly turn into a disaster, allowing salty moisture, foul-smelling organic odors, and raw waste foam to spit onto your rear aquarium glass and flooring. Swapping out a broken or missing top cover with this original factory replacement restores full containment, keeping your aquarium cabinet clean and your surrounding living area completely free of salt spray.
Key Features
True Factory Sizing Matrix: Machined to fit the exact diameter profiles of the wide Classic 2000HOB wastewater collection cup perfectly.
Light-Blocking Opaque Material: Dark black composition creates a natural shade barrier over the fractionating neck, preventing intense aquarium LED arrays from fueling thick film algae inside the cup.
Polished Structural Edge Profiles: Fully rounded and smoothed edge rings resist chipping and provide a comfortable grip for your fingertips during removal.
Saltwater-Inert Resilience: Fabricated entirely from marine-grade acrylic that handles direct, non-stop exposure to aggressive organic wastes and salt creep without degrading.
Verified Hardware Compatibility
Reef Octopus Classic HOB Series: Sized explicitly for the wide-body Classic 2000HOB (alternatively labeled as the BH-2000) hang-on back external skimmer.
(Note: This lid is configured exclusively for the wide diameter metrics of the 2000HOB footprint. Alternative skimmer frames, such as the Classic 90HOB, 100HOB, or 1000HOB, utilize different top dimensions and require their respective model-specific lids).
What’s Included:
(1) Reef Octopus Replacement Classic 2000HOB Black Acrylic Collection Cup Lid
(Note: Clear acrylic collection cups, neck alignment O-rings, cup drain fittings, and primary skimmer body towers are sold separately).
Technical Specs:
Official Manufacturing Title: Reef Octopus Classic HOB Top Cover / Collection Cup Lid (2000HOB Variant)
SKU / Factory Part Identifier: ROP-CCLID-BH2000
Material Composition: 100% High-Density Saltwater-Safe Opaque Black Acrylic
Assembly Profile: Recessed Drop-In Slip Placement
Primary Function: Salt Spray Containment, Odor Shielding, & Air Venting Management
- Turn off your protein skimmer's pump power supply to temporarily stop foam production before handling the upper containment components.
- Remove your existing damaged or cracked collection cup lid by lifting it straight up off the clear acrylic reservoir rim.
- Take a soft cloth dampened with warm fresh water and wipe down the upper seating lip of your clear collection cup to clear out dried salt crust.
- Align the recessed lower lip guide of your new ROP-CCLID-BH2000 lid face-down over the open mouth of the collection cup.
- Lower the lid smoothly into position, ensuring the alignment lip seats flush all the way around the inner wall of the cup rim without wobbling.
- Turn your skimmer pump back on and verify that air vents freely through the lid's integrated exhaust holes as foam begins to build.
Pro Tips:
- Clean the Integrated Exhaust Vents Weekly. Because popping saltwater bubbles carry minuscule traces of organic fish waste, a fine, gummy film of sludge and salt creep will naturally build up right over the ventilation holes on top of the lid. If these holes become completely clogged, air cannot escape from the skimmer body. This creates localized air pressure that will forcefully push the water level down inside the neck, completely stalling your skim performance or causing the skimmer to flood erratically. Rinse the lid under warm tap water weekly to keep the vents clear.
- Never Use Alcohol-Based Cleaners on Your Acrylic Lid. When removing organic odors or brown film from your replacement lid, never spray it with household glass cleaners, rubbing alcohol, or surface sanitizers. High-purity chemical solvents break down the molecular bonds of cast acrylic, triggering an immediate structural failure known as "crazing." This will transform your pristine black lid into a web of thousands of tiny, brittle hairline cracks that will break under light pressure. Stick exclusively to fresh warm water and a soft microfiber towel.
- Avoid Shoving Tubing Tightly Through the Vent Holes. While it might be tempting to use the lid's vent openings to anchor flexible air tubing or specialized ozone return lines, do not block or shove tight-fitting plugs into these holes. The total surface area of the integrated factory vents is calculated precisely to match the heavy air-draw volume of the Aquatrance pump. Restricting this open airflow pathway compromises the skimmer's delicate internal vacuum dynamics, leading to inconsistent bubble creation and unstable water levels.
