When it comes to selecting the ideal auto top-off (ATO) system for your new tank, the debate between the Tunze Osmolator and the Red Sea Reef ATO+ has sparked various opinions within the reefing community. Both systems offer unique features and benefits. The Tunze Osmolator is praised for its reliability and accurate water level detection, making it a favorite among reef enthusiasts who prioritize precision. On the other hand, the Red Sea Reef ATO+ is applauded for its ease of setup and compatibility with Red Sea tanks. However, success stories extend beyond these two options. Many hobbyists have also found satisfaction with alternative ATO systems, such as the Neptune Systems ATK or the IceCap ATO.
