The Trigger Systems Crystal ATO 5 Gallon is an essential component for maintaining a stable saltwater reef aquarium environment. This automatic top-off reservoir is designed to replenish evaporated water in your display tank or sump, ensuring consistent salinity and water levels without the need for constant manual intervention. It helps prevent drastic fluctuations in specific gravity, which can be detrimental to delicate corals and fish.

Crafted from durable 1/4″ thick material, this 5-gallon reservoir resists bowing and features a beautifully rounded and polished top edge. Its compact dimensions of 6″ long x 14″ wide x 15″ tall allow for flexible placement within your aquarium setup. The unit includes a secure lid to minimize evaporation from the reservoir itself, along with two 0.25″ OD hose ports and a dedicated opening to neatly manage wires and hoses for your ATO pump and sensors.

This ATO reservoir is ideal for reef hobbyists and aquarists seeking to enhance the stability and health of their marine ecosystems. By automating the top-off process, it significantly reduces daily maintenance tasks and provides peace of mind that your water parameters remain consistent. It is a perfect addition for anyone looking to achieve a more robust and thriving reef tank with minimal effort.
