Red Sea ReefRun G2 Controllable DC Pumps

Red Sea ReefRun G2 Controllable DC Pumps

Red Sea ReefRun G2 Controllable DC Pumps are next-generation return pumps for saltwater aquariums, built to deliver precise, powerful water circulation with near-silent running. They suit reef keepers who want adjustable flow straight out of the box, with the option of smart control later.

Key Benefits

• Next-generation return pump with an adjustable flow rate for optimal water movement
• Integrated flow controller, so the pump works stand-alone
• Virtually silent performance for a quieter room
• Energy-efficient DC design that runs at low energy and helps lower long-term running costs
• 180° rotating outlet for flexible installation
• Inlet flow guide to help prevent air intake
• Universal connectors for easy integration into a variety of setups
• Extra-long 10-foot power cable with convenient connector placement, which makes maintenance easier

How to Use

Use the built-in flow controller to set the pump's output in stand-alone operation. For advanced scheduling, alerts and automation, pair the pump with the ReefRun Dual Controller (sold separately) and the ReefBeat App. Rotate the outlet through its 180° range to suit your plumbing layout, and fit the outlet adapter that matches your pipe or hose.

Frequently Asked Questions

Do I need a separate controller to run this pump?
No. The pump has an integrated flow controller for stand-alone operation. The ReefRun Dual Controller (sold separately) is only needed if you want app-based scheduling, alerts and automation.

How do the two models differ in flow?
The G2 4000 delivers 530-1060 GPH with a max head height of 11.2 ft (3.4 m). The G2 12000 delivers 1300-3200 GPH with a max head height of 19 ft (5.8 m). Compare these ranges with your plumbing and the flow you need when choosing.

Is the pump noisy?
It is designed for virtually silent performance, so it suits living areas where noise matters.

Can I change the direction of the outlet?

The G2 4000 supports a 3/4" PVC pipe adapter, a 5/8" / 1" hose barb and a male threaded 3/4" gas fitting. The G2 12000 supports a 1" / 1-1/4" PVC pipe adapter, a 1" / 1-1/4" hose barb and a male threaded 1" gas fitting.
