LINLAN Aquarium Inline CO2 Diffuser - Center Disc with Viewing Window, High Dissolution Rate, Essential for Low/Medium Flow Systems, Fits 1/2"(12mm) ID Filter Hose

• 【Essential for Low/Medium Flow Systems】Engineered to optimize common filter flow rates. Produces ultra-fine misting and efficient CO₂ dissolution without requiring high flow speeds.
• 【Efficient & Uniform CO₂ Diffusion】 The center-positioned ceramic disc generates CO₂ bubbles. Water accelerates around both sides of the disc, 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.
• 【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.
• 【Aquascaping Freedom】No longer restricted to placing a diffuser near the outflow. Your layout, hardscape, rocks, wood, and foreground carpet are driven purely by aesthetics – not by equipment constraints.

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 construction：The main body is made of lightweight, sturdy, corrosion‑resistant aluminum alloy, with all parts detachable for easy cleaning or replacement of the ceramic disc. Viewing window：An integrated viewing window made of high‑clarity, pressure‑resistant PC allows you to see the operating status at a glance. High-efficiency atomizing core：High-precision ceramic disc provides a larger atomizing surface than standard flat discs, producing finer, longer-lasting bubbles at lower starting pressure for significantly better dissolution. Low-pressure operation, long-lasting：Works at low pressure (3 kg), resists clogging, easy to maintain, and built to last. Secure connections：Both filter hose and CO₂ tubing connections use locking nuts for double protection against pressure fluctuations – no leaks, no 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, high-clarity PC Atomizing component: Precision ceramic disc Package includes: 1x Inline CO₂ Diffuser 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. Rinse with clean water or wipe gently with a soft cloth. Ingredients Aluminum alloy
