MagTool Green Auto Top Off System for Saltwater & Freshwater Aquariums

Experience a smart approach to maintaining water levels with MagTool's Auto Top Off system. Equipped with dual optical sensors, it tracks when to replenish water and prevents overflows, helping your reef or display tank stay balanced without constant monitoring.

How it works

The system uses two high-precision optical sensors. One monitors your tank’s water level and triggers a gentle refill, while the other acts as a safety valve to prevent spills.

• Dual High-Precision Optical Sensors: one for level monitoring, the other for overflow prevention.
• Startup assessment and refill duration calculation with safeguards against accidental overfills.
• Compact, space-saving design: 0.8-inch footprint and 1mm sensors suitable for rimmed or rimless tanks.
