• Automatic refilling of evaporated water with built-in protection against dry running of the pump.
• Easy installation thanks to a magnetic holder that securely attaches the sensor to the glass.
• Complete system including DC pump, 2 meter hose (6/9 mm), anti-siphon valve, hose clamp and power adapter.
• Compact and quiet design, ideal for placement in sump or back wall compartment.

Technical specifications

• Maximum flow rate: approximately 280 l/h
• Power: 4 W
• Power supply: 12 V DC
• Maximum delivery head: ± 2.2 m

Advantages

• Automatically keeps water levels stable – no more daily checks required.
• Prevents salt fluctuations and stress in corals and fish.
• Reliable protection against overflowing and running dry.
• Compact size that fits into virtually any aquarium setup.

Usage tips

Place the sensor at the desired water level and ensure it remains free of algae and debris. Check the reservoir regularly and refill it with reverse osmosis or demineralized water. The anti-siphon valve prevents backflow when the pump is switched off.
