The Chihiros Dosing Flow Adapter is a premium inline accessory designed to integrate your liquid fertilizer dosing system directly into your aquarium’s filter outflow. Made from anodized aluminum, it installs between your canister filter hoses (12/16mm or 16/22mm) and allows for a clean, concealed nutrient delivery system. It features four dosing ports, each with a built-in one-way valve to prevent any chance of leakage or backflow. Importantly, unused dosing ports remain sealed — so you can confidently use just one or two lines without needing to plug the others. This makes it ideal for low-tech and high-tech setups alike.
