Red Sea ReefCan Auto Top Off Reservoir 40L

Red Sea ReefCan Auto Top Off Reservoir 40L

Red Sea ReefCan Auto Top Off Reservoir 40L is a vertical RO water reservoir for reef aquarists who want to store more top-off water in a compact footprint. It is designed to hold the ReefATO+ system and to make installation and routine maintenance easier. It suits ATO setups in an aquarium cabinet where floor space is limited.

Key Benefits

• Space-saving vertical design that uses unused vertical space in your aquarium cabinet, so you can store more water without enlarging your system's footprint.
• Durable, transparent body with a precisely embedded water scale, so you can check water levels at a glance without opening the reservoir.
• Front opening for easy refilling and a rear opening for cable and tube management, so you don't have to juggle tubes and cables during setup or maintenance.
• Rear access point large enough for any ATO pump up to 2.3" (5.8 cm) in diameter, so it works with a wide range of equipment.
• Made to hold the ReefATO+ syphon breaker. Once the cables are set up, you only need to disconnect them for occasional pump maintenance.

Suitable For

• Reef keepers who want to maximise RO water storage without giving up valuable floor space.
• ReefATO+ users, as the reservoir is specifically designed around that system.
• Most other ATO systems, provided the pump fits the 2.3" (5.8 cm) diameter rear opening.
