Copexa Core - Coming Soon!

The Copexa Core is a flexible, programmable hydrogen delivery system designed for marine and freshwater aquariums up to 100 gallons. It provides operators with the hardware needed to actively target oxidative stress and investigate cellular stability in their own controlled environments.

Engineered for easy movement across all your setups, the compact modular unit with a top handle simplifies multi-tank care. One system can seamlessly provide specialized support across acclimation setups, quarantine systems, and main display tanks.

Control output with ease. Switch between reliable flow rates of 150 ml/min and 300 ml/min, then select from four intuitive preset pulse modes for consistent, set-and-forget hydrogen dosing. For complete operational versatility, the system is fully compatible with modern aquarium controllers and basic external timers.

A complete high-performance kit. Each unit includes a high-dissolution acrylic tube reactor, a durable stainless steel nano-diffuser, and a dedicated ventilation fan kit for safe and reliable operation.
