Octo Aquatrance 32mm Output Adapter (XS225 / CLSC-225)
SKU: ROP-AQOA-225
100% Genuine OEM Factory Part: Manufactured directly by Reef Octopus as an exact structural match to replace cross-threaded or calcified discharge unions.
Precise 32mm Internal Calibrations: Molded with high-precision metrics to cleanly seat standard ø32mm internal skimmer riser pipes and diffusion grids.
Heavy-Impact Black PVC Core: Infused with an inert, saltwater-safe polymer matrix that resists structural stress cracking and salt-creep breakdown.
Restores Tight Hydraulic Seals: Prevents processed air-and-water foam from leaking around the base tracks before it can reach the main reaction neck.
Explicit Space-Saver Compatibility: Tailored specifically to handle the ultra-tight internal engine plumbing paths of XS225 and CLSC-225 skimmer bodies.

Reef Octopus Aquatrance 32mm Output Adapter for XS225 & CLSC-225 (SKU: ROP-AQOA-225)
The Reef Octopus Aquatrance 32mm Output Adapter (SKU: ROP-AQOA-225) is an authentic, internal OEM plumbing replacement component distributed by CoralVue to protect high-density bubble columns inside specialized space-saver protein skimmers. In space-saver (SSS) configurations, the pump engine is tucked directly inside the main reaction chamber cone to keep the overall equipment footprint as small as possible. Because the pump operates completely submerged inside the bubbling water column, the discharge adapter neck handles constant vibration, thermal changes, and backpressure. Over years of use, the internal plastic tracks can crack, or become cross-threaded during routine deep cleanings. If a leak develops at this connection, the air-and-water mixture will bleed out into the bottom plate, disrupting your skimmer's performance.
Molded from high-grade, impact-resistant black PVC, the ROP-AQOA-225 is engineered to slip or thread directly onto the pump's front output line, presenting a robust 32mm opening. This adapter is built to align with the unique space-saving geometries of the legacy Diablo XS225 and the heavy-duty Classic 225-INT / 225-SSS Space Saver skimmer assemblies. By restoring a tight hydraulic connection between your pump motor and the primary bubble diffusion plate, this factory part ensures all generated micro-bubbles are forced straight up into the neck to build a thick waste foam.
Key Features
Maintains Consistent Micro-Bubble Pressure: Forces the dense air-and-water mixture directly through your skimmer's diffuser holes, preventing premature foam collapse.
Tool-Free Plumbing Overhauls: Precise slip-and-thread tolerances let you pull your pump and riser assembly apart for quick cleaning without tools.
Inert, Reef-Safe Construction: Engineered from specialized marine polymers that will never leach chemical stabilizers or toxic compounds into delicate coral systems.

- Unplug your Reef Octopus space-saver skimmer pump from its electrical wall outlet. Lift the entire skimmer out of your sump and move it to a clean workspace.
- Remove the collection cup, and gently unscrew or slip off the internal bubble diffusion plate assembly to expose the pump tucked into the skimmer floor.
- Locate the old, worn output adapter. Twist or slide it away from the pump's main discharge nose. Pro Tip: If dried salt crust or calcium deposits have locked the plastic parts together, soak the pump assembly in warm water and white vinegar for 10 minutes to dissolve the scale before pulling.
- Clean the pump's discharge nozzle with a soft towel to clear away any remaining slime or organic film.
- Push your fresh ROP-AQOA-225 output adapter firmly onto the clean pump discharge nozzle until it seats squarely against the shoulder stop.
- Re-align the 32mm vertical riser pipe or diffuser plate assembly with the top of the new adapter port. Slip the parts back together flush, slide the pump into its floor-retention tracks, and lower the skimmer back into your sump chamber.
Pro Tips:
- Always Verify Your Exact Space-Saver Skimmer Body Model Before Ordering. Because Reef Octopus uses several types of 32mm adapters across their modular plumbing lines, it is incredibly easy to select the wrong part variant by mistake. This specialized ROP-AQOA-225 Adapter is built with a custom thickness and length specifically for internal space-saver models like the Classic 225 or Diablo XS225. If you are trying to attach a standalone pump to an external return line or an older non-space-saver skimmer, you will likely need a standard flanged option like the ROP-OA-32THK instead. Double-check your skimmer's official label to ensure a perfect, no-leak fit.
- Apply a Drop of Fresh RO Water to Act as a Safe Plumbing Lubricant. Because this OEM adapter is molded to exceptionally tight tolerances to prevent internal pressure leaks under heavy water flow, sliding it dry onto a hard plastic pipe can sometimes feel incredibly tight. To make your installation easier, wipe a tiny drop of fresh RO water inside the slip ports. This allows the parts to slide together smoothly and helps you line up your alignment angles without over-stressing or fracturing the plastic.
- Never Use Harsh PVC Primers or Solvent Cements on This Adapter. Even though this replacement adapter is molded out of black PVC, you should never use standard purple primers or permanent PVC solvent cements to lock it into your skimmer. Reef Octopus space-saver skimmers are engineered to rely entirely on precision friction-fit seals so you can completely take them apart for routine maintenance. Gluing the adapter down permanently prevents you from removing the pump engine or descaling the internal needlewheel, eventually ruining your skimmer's lifespan.
