UNS Reef System ATO

The auto top off (ATO) system for the Ultum Nature Systems Reef System increases water capacity and reduces the need for frequent water level monitoring. It features a proprietary soft-close refill drawer for spill-free refills using the included funnel, automatically regulating water levels to compensate for evaporation and reduce salinity fluctuation. Includes the ATO, a float valve, and a refill funnel. Designed specifically for compatibility with the UNS Reef System aquarium series; available for R60, R90, R120, R150, and R180 models.
