The Red Sea ReefCan 18L Reservoir is a smart and space-efficient solution for maintaining your aquarium’s water levels. Designed to support auto top-off (ATO) systems, it holds enough RO water to serve a 200-litre aquarium for about a week. Its transparent housing with an integrated water scale ensures you can easily monitor the remaining water, while the tall, slim design maximises capacity without occupying excessive cabinet floor space.

Key Features:

• 18L capacity, ideal for auto top-off systems in 200-litre aquariums.
• Slim, space-saving design fits neatly inside technical cabinets or behind tanks.
• Transparent housing with integrated water scale for easy monitoring.
• Refillable without removing the container or disconnecting hoses.
• Utilises height to maximise capacity while conserving cabinet space.

The Red Sea ReefCan 18L is a practical and efficient reservoir for hobbyists, offering convenience and functionality to keep your aquarium’s water system running smoothly.
