About this item
- Upgraded 2.0 ATO System：The 2.0 ATO system ensures efficient daily water level maintenance for saltwater and freshwater tanks, making it ideal for use during trips or holidays. The upgraded interface allows you to easily start, pause, or resume the system with the FZ button
- Compact and Versatile Design：The optical sensor measures just 0.79 inches in diameter, making it suitable for rimmed, rimless, or sump tanks. Dual sensors, spaced 0.1 cm apart, monitor water levels with precision, maintaining a difference of only 0.6 cm. Recommended for tanks with wave fluctuations under 1 cm.
- Enhanced Safety Features：QST 2.0 technology provides real-time overfill protection. The system stops the pump and triggers an alarm if refilling exceeds six times the preset limit. It also detects sensor issues and low reservoir levels for added safety.
- Quiet Micro Pump：The compact pump fits tanks with neck sizes over 1.97 inches, offering a flow rate of 74 gallons per hour and a lift height of up to 2 meters. Optimized operation reduces unnecessary activations, extending pump life.
- Complete Accessories Included：The set includes strong magnets (compatible with tank walls up to 0.78 inches thick), a check valve to prevent backflow, and a 6-foot (180 cm) tube for quick installation.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
