LINLAN Aquarium Inline CO2 Diffuser – Side Disc with Built-in Check Valve, Essential for High Flow Systems, Fits 16mm (5/8" ID Filter Hose

• 【Essential for High Flow Systems】Features a side-mounted ceramic disc with a large internal chamber. Relies on direct water flow impact to strip and atomize CO₂ – simple, reliable, and ideal for high-power, high-flow filter systems.
• 【Efficient & Uniform CO₂ Diffusion】 The side‑mounted ceramic disc generates CO₂ bubbles. Water flowing past quickly carries the bubbles away, instantly atomizing CO₂ into ultra‑fine bubbles that spread evenly throughout the aquarium – ensuring maximum plant uptake.
• 【External Installation】Installs on the filter outlet hose, taking up no space inside the tank. Preserves your aquascape’s clean look and eliminates visual clutter caused by in-tank diffusers.
• 【Built-in Check Valve】Integrated one-way check valve automatically closes when CO₂ stops, preventing water backflow from damaging your CO₂ equipment – safer and more reliable.
• 【Maintenance-Free】Placed outside the tank away from light, so algae and biofilm never develop. The precision ceramic disc resists clogging and delivers long-term reliability when used with a pressurized CO₂ cylinder.

Product description In-tank CO2 diffusers that obstruct the view, disrupt the layout, and often fail to achieve complete CO₂ dissolution. The LINLAN Inline CO₂ Diffuser brings professional efficiency and unobstructed aesthetics within easy reach, helping you create a thriving underwater landscape. Key Configurations Aluminum alloy body： Lightweight, corrosion-resistant aluminum for long-term durability in aquarium environments. Side-mounted high-efficiency atomizing system： The core uses a side-mounted ceramic disc. As water flows past, it carries out ultra-fine bubbles – no large bubbles remain, atomization is uniform and efficient, dramatically improving dissolution rates. Large internal chamber： Optimized internal cavity design provides ample space, creating near-zero resistance to filter flow – ensuring your tank’s circulation power remains unaffected. Secure connections： Water hose connection secured with stainless steel hose clamps; CO₂ tubing connection secured with a locking nut – double protection against pressure fluctuations, no leaks or disconnections. Specifications Hose connection size: Fits 1/2" ID (12mm) or 5/8" ID (16mm) filter hose (select at purchase) CO₂ tubing connection size: Fits 5/32" ID (4mm) CO₂ tubing Body material: Aluminum alloy Atomizing component: Side-mounted ceramic disc Package includes: 1x Inline CO₂ Diffuser, 2x Stainless steel hose clamps Precautions Be sure to use CO₂-rated tubing only. Do not use standard air tubing, as it may loosen or burst due to insufficient pressure resistance. When cleaning, do not use hard or sharp objects to scrape the ceramic disc surface, as this will damage its micro-pore structure. Ingredients Aluminum alloy
