Reef Octopus
Globally trusted for premium protein skimmers and pumps, engineered in-house for unmatched reef filtration performance.
Pristine Under-Cabinet Defense: Restricts bubbling foam matrices within the collection chamber, eliminating messy salt spray and moisture weeping.
Optimized Pressure Venting: Allows necessary internal air loop exhaust without letting escaping foam residue pool onto surrounding wires.
Color Matched Hardware: Revitalizes your sump configuration by blending natively with classic red plumbing unions, pump blocks, and skimmer neck cones.
Toolless Installation Loop: Simply drop the cover flat over the top of your existing matching collection cup cylinder rim—no retrofitting required.
Genuine CoralVue OEM Part: Manufactured to meet strict factory tolerances, ensuring an airtight, rattle-free fitment that generic covers cannot match.

(Note: If you own a black-accented Super Reef Octopus SRO-1000INT or a white-accented Extreme XP-1000INT, their cups share the exact same physical 120mm diameter footprint, allowing this red lid to function as a direct color-customized replacement alternative)

Turn off your protein skimmer's primary venturi pump block to allow the internal foam line inside the neck to collapse safely.
Carefully pull the collection cup assembly upward from the main skimmer body neck and carry it over to a sink or wash station.
Dispose of all accumulated liquid waste skim from the cup into your drain plumbing.
Clean the upper lip of the collection cup rim with warm fresh water to wipe away dried organic crusts or salt deposits.
Unpack your new 120mm Red Replacement Lid and align its concentric indexing collar square over the top opening of the clean cup.
Press the cover downward gently until it seats flush and level, then lower the completed cup back into the main skimmer neck tracking track.
- Verify Your Cup Diameter Before Purchasing. Reef Octopus produces dozen of skimmer shapes that look identical in catalog listings. The 120mm sizing indicates the outer metric diameter framework of the lid itself, not the air neck tube size or overall skimmer width. This cover is optimized exclusively for 4-inch diameter skimmer body lines. Always take a metric ruler or digital caliper and measure across the top opening of your current collection cup rim to ensure it matches 120mm exactly before final ordering.
- Avoid Abrasive Chemical Cleaners. When washing out your replacement lid during weekly maintenance checks, only use warm tap water and a soft micro-fiber towel or gentle sponge. Never scrub the acrylic or polymer plastic with rough steel wool pads, or use harsh bathroom chemical sprays, alcohol, or window cleaners. These aggressive solvents can cause micro-scratching on the plastic surface, leading to structural micro-fracturing and premature clouding.
- A Smart Option for Color-Customizing Black or White Models. If you own an older or alternative-series skimmer line like the SRO-1000INT (which traditionally ships with a black lid) or an XP-1000INT (which ships with a white lid), you can use this 120mm red version as an easy color upgrade. Because Reef Octopus utilizes standardized metric tooling dies across their production runs, this red lid will transition onto any 120mm collection cup cylinder, allowing you to match a red-themed custom sump manifold cleanly.
