Automatic Top Off Systems for Reef Aquariums
Maintain the perfect water level in your marine aquarium with our auto top-off systems (ATO osmolators). These automated systems compensate for evaporation, preserve salinity, and ensure stable parameters for your reef tank.

- Complete Auto Top Off Kits – Ready-to-install systems with pump, sensors and reservoir

Why Use an Auto Top Off System?
Evaporation in reef aquariums causes salinity spikes that stress corals and fish. An automatic osmolator adds fresh water to maintain constant levels, protecting your animals and reducing maintenance.
