The ReefCan Reservoir
More RO water for less floor space.
The ReefCan 40 can supply the ATO of a 500-litre tank with enough water for about a week.
Fits in the sump cabinet or behind the tank, and be refilled without having to remove the reservoir and disconnect its tubes & cables.
A transparent plastic body with an embedded water scale allows you to see how much RO water is left.
