The Neptune Systems 2-Channel Apex to Tunze Stream Cable is a specialized accessory designed to seamlessly integrate your Tunze Controllable Stream pumps with your Neptune Apex aquarium controller. This cable allows your Apex system to directly communicate with and manage the functions of up to two Tunze pumps, unlocking a new level of automated flow control within your reef aquarium. By connecting your pumps to the central brain of your tank, you can create sophisticated and naturalistic water movement patterns that benefit your corals and other inhabitants.

This durable cable assembly features a single RJ45 connector on one end, which plugs directly into an available AquaBus port on your Apex base unit or a compatible module. The other end splits into two 5-pin DIN connectors, each designed to plug into the controller port of a Tunze Controllable Stream pump. This configuration simplifies wiring and eliminates the need for multiple timers or separate controllers, providing a clean and efficient setup for managing your tank's circulation.

This product is essential for any advanced reef aquarist who owns both a Neptune Apex system and compatible Tunze Stream pumps. If you want to move beyond the basic settings of your pumps and leverage the full power of the Apex Fusion interface for creating custom flow schedules, feed modes, and dynamic wave patterns, this cable is the key. It empowers you to centralize your equipment control, creating a more stable, automated, and thriving reef ecosystem.
