The AquaPro EC Series External Inline CO₂ Diffuser is the professional solution for aquascapers who want to maintain a clean, equipment-free look inside their aquarium while maximizing CO₂ performance. Designed for use with external canister filters, this diffuser installs directly into your outflow tubing, delivering an ultra-fine CO₂ mist that is fully absorbed before the water even reaches the tank.
Crafted from a durable gunmetal aluminum alloy, the EC Series is built for longevity and resistance to corrosion. Its high-quality ceramic membrane produces consistent, micro-sized bubbles, significantly increasing the contact time between CO₂ and water compared to standard in-tank diffusers. This ensures better efficiency and drives the lush, healthy growth that advanced aquascaping requires.
Inline Design: Installs neatly on your canister filter's outflow hose, keeping your display tank free of glass or plastic clutter.
Maximum Dissolution: The integrated ceramic membrane produces ultra-fine bubbles for superior CO₂ absorption into the water column.
Premium Construction: Precision-machined from gunmetal aluminum alloy for a professional look and long-lasting durability.
Easy Installation: Simple setup involves cutting the outflow hose and securing the diffuser with the included fittings.
Flexible Sizing: Available in multiple tubing sizes to fit standard filter setups: 12/16mm, 16/22mm, and 20/25mm.
Professional Aesthetics: Maintains the focus on your aquascape by hiding technical equipment beneath the cabinet.
