If you’re trying to grow demanding stems, dense carpets, or rare buce, consistent CO₂ delivery is key. But bulky diffusers, suction cups, and messy tubing can distract from a clean aquascape. The UNS Pro Inline CO₂ Diffuser fixes that by installing directly into your canister filter’s outflow line, hidden under the cabinet. It diffuses CO₂ into the water before it reaches the tank, and its side‑mounted ceramic disc prevents clogging and flow loss, something many inline diffusers struggle with. Key Features & Benefits An integrated inline design eliminates in-tank equipment clutter, keeping diffusers and tubing out of your main display. The innovative side-mounted ceramic disc design guarantees zero flow obstruction, keeping your canister filter running at peak turnover. Blending gas directly into your filter’s return line, it creates an ultra-fine micro-bubble mist for maximum plant absorption and unmatched tank coverage. The external, side-accessible chamber design makes routine cleaning or ceramic disc replacements incredibly quick and simple. Product Specifications Installation Position: External Filter Outflow Line (Return side only) Bubble Quality: Ultra-Fine Micro-Pore Atomization System Integration: Seamlessly matches UNS Delta and Blitz Canister Filters, as well as all other major canister filter brands, using standard flexible hosing.
