Red Sea ReefCan – RO Water Reservoir

Red Sea ReefCan is a slim, space-efficient RO/DI water reservoir designed for automatic top-off systems in reef and marine aquariums.

Unlike traditional reservoirs that take up valuable cabinet floor space, ReefCan uses the normally unused vertical space inside the aquarium cabinet. Its tall, narrow design provides generous water storage while leaving more room for dosing equipment, controllers and other aquarium hardware.

Designed for ReefATO+

The rear opening is designed to accommodate an ATO pump and associated tubing while keeping the installation neat and organised.

The opening can accommodate pumps up to approximately 5.8cm in diameter, and the cap is designed to securely hold the siphon breaker supplied with Red Sea ReefATO+.

Once installed, the pump and tubing can remain in position while the ReefCan is refilled through the separate front opening, reducing the need to disconnect equipment during normal maintenance.

Easy Water-Level Monitoring

The transparent reservoir body and built-in measurement scale make it easy to see how much RO/DI water remains at a glance.

This helps make top-off maintenance more predictable and allows you to quickly determine when the reservoir needs refilling.

Ideal For

• Red Sea REEFER aquariums

• ReefATO+ installations

• Reef and marine aquariums using automatic top-off systems

• Cabinets where floor space is limited

• Aquarists wanting a clean and organised RO/DI reservoir solution

Red Sea ReefCan provides a simple and practical way to increase top-off water capacity while using significantly less valuable cabinet floor space than a conventional reservoir.
