IceCap K3 150/200 HOB Skimmer Bubble Stopper
Operating high-capacity hang-on-back protein skimmers on marine aquariums requires heavy organic waste extraction without filling the display tank with unsightly microbubbles. The IceCap K3 150/200 HOB Bubble Stopper (SKU: IP-K3200H-BS) is the official OEM replacement bubble trap chamber engineered specifically for IceCap K3 150HOB and K3 200HOB Hang-On-Back Protein Skimmers.
When high-performance protein skimmers fractionate large volumes of organic compounds, fine air bubbles inevitably escape into the return outflow stream. In sumpless aquarium setups, these bubbles enter the main display tank, creating a hazy appearance and potentially irritating delicate corals and marine fish. The IP-K3200H-BS mounts directly at the water exit spout, utilizing an enlarged baffle chamber and deflector mechanism to pop and trap escaping microbubbles while allowing clean, de-aerated water to gently re-enter the aquarium.
Ideal Replacement Scenario
If your existing K3 150HOB or K3 200HOB bubble trap box has cracked, become brittle from handling, or was lost or damaged during tank maintenance, replacing it with the authentic IP-K3200H-BS restores crystal-clear water return and prevents microbubble clouding.

Installation & Replacement Guidelines:
Turn off power to the skimmer pump before servicing the return plumbing.
Carefully detach the old or damaged bubble stopper box from the skimmer outflow pipe.
Rinse the new IP-K3200H-BS bubble stopper in fresh RO water to remove any manufacturing dust.
Slide the inlet coupling of the bubble stopper onto the outflow discharge pipe until securely seated.
Restore power to the skimmer pump and adjust the water exit height to ensure smooth, splash-free return flow into your aquarium.
Pro Tips:
- Position Just Below the Aquarium Water Surface. For optimal noise reduction and microbubble dissipation, position the bubble stopper discharge so water gently cascades right at or slightly beneath the tank water surface. This prevents water splashing sounds and stops bubbles from being driven deep into the display.
- Rinse Buildup During Regular Water Changes. Algae and biofilm can accumulate on the inner baffle surfaces of the bubble stopper over time. During your routine water changes, give the bubble stopper a quick rinse under warm tap water to prevent organic buildup from restricting return flow.
