Installed the Level-O in my nano reef tank and it’s been working perfectly. The sensor is very accurate and the pump runs quietly. No overflows even during heavy water changes. Simple to set up and fits well in my tank setup.
Alexander Watson –
This is the smallest ATO I’ve seen and it fits perfectly in my compact tank. The dual optical sensors prevent overflow and the water level stays stable. Works seamlessly with my Reef Casa all-in-one system.

Great precision in maintaining water levels. The installation took less than 10 minutes. Only downside is the sensor cable is a bit short for larger tanks, but still very reliable for my nano setup.
