Trigger Systems Emerald Green ATO Reservoir 5 Gallon
Emerald Green ATO reservoirs feature crystal clear acrylic with an elegant emerald top, to hold top off water for your aquarium in a closed container. The Trigger Systems ATO containers have a removable lid to prevent excess evaporation, while providing a large opening to refill and clean the reservoir as needed.
Each ATO reservoir has two 0.25” OD holes for tubes to be plumbed through, or wires for float switches.
The Ruby, Crystal, Sapphire, Amethyst, and Emerald lines of ATO reservoirs have laser engraved water level markings so you can monitor how much water your tank is using.
