Auto Top Off Systems

An Auto Top Off (ATO) system is a great investment for saltwater aquarium owners because it helps maintain steady salinity levels. When water evaporates, the salt stays behind. Increasing salinity levels, which if left unchecked for too long, can stress fish and coral. The ATO system senses when the water level gets low and adds fresh water, keeping everything just right for the tank inhabitants and eliminating the need for daily manual top-offs.
