Aquarium Auto Top Off System with Triple Safety, Sealed Sensor & Magnet Mount

Aquarium Auto Top Off System – Triple Safety, Sealed Sensor & Magnet Mount

Maintain a more stable aquarium water level with this advanced Auto Top Off system designed for freshwater, saltwater, and reef tanks. A vacuum-sealed sensor, adaptive water-level control, dry-run protection, and high-level shutoff work together to support reliable automatic top-offs while helping reduce flood and pump-failure risks.

Key Benefits

• Triple Safety Protection: High-level shutoff, dry-run protection, and anti-siphon safeguards help reduce the risk of overfilling and pump damage.
• Vacuum-Sealed Sensor: Double-layer sealing helps protect internal components from moisture, salt creep, and corrosion.
• Adaptive Water-Level Control: Automatically adjusts top-off volume based on evaporation within approximately a 1–4 mm range.
• Pump Protection: Real-time pump monitoring stops operation when the reservoir runs dry to help prevent unnecessary burnout.
• Strong Magnetic Mount: Secure magnetic installation supports aquarium glass up to approximately 19 mm thick.
• Integrated Controller Design: Fewer external components and connection points create a cleaner setup with fewer potential failure points.
• Optimized Top-Off Pump: Included low-suction pump is designed for frequent start-stop operation and efficient reservoir use.

Reliable Water-Level Control for Reef & Freshwater Tanks

The sealed sensor continuously monitors aquarium water level and activates the top-off pump as needed. A protective sensor cover helps reduce interference from bubbles or debris, while the magnetic tubing holder keeps the refill line securely positioned for a cleaner, more organized installation.
