Keep your aquarium stable and healthy with the Ultum Nature Systems Dual All In One ATO. This reliable auto top-off system automatically replenishes evaporated water, preventing salinity fluctuations that can stress fish and coral. Designed for easy maintenance, an ATO ensures a balanced, healthy environment while reducing the need for manual top-offs. Although ATO (automatic top-off) systems are commonly used in saltwater aquariums, this versatile device is also suitable for freshwater setups, making it a valuable tool for all aquarium hobbyists.
