Review on 🐠 Advanced Dual-Sensor XP Aqua Duetto Auto Top Off ATO for Complete Aquarium Maintenance by Beth Martin

This thing is amazing. It's so compact and easy to install. I installed it in 30 minutes including the time it took to drill and run a hose through my "reservoir" to get it as clean as possible. The sensors are very sensitive to the water level, which is great as the failsafe stops at any moment. It's also great that there are audible warnings when the tank is empty, clogged etc. Of course it also has a feature that detects when the pump is running too long and shuts it off. The hose is nice and solid, the controller is solid, and the system is clear. Overall, don't spend hundreds on an ATO when it's perfect for a fraction of the money!
