Description
xKeep your aquarium at a steady water level with the Qwakay Auto Top Off System. This intelligent kit helps counter evaporation, minimize fluctuations, and support stable conditions for fish and corals. The system runs on a safe 12V supply, delivering energy efficiency and peace of mind in daily maintenance.
Smart sensing and alarms are built in to help you respond quickly. If the fill bucket is empty, the water tank leaks, the float sticks, the refill timer times out, the pump isn’t connected, or there’s a short circuit, the system will trigger an alert so you can check and adjust before the tank shows signs of stress. The integrated pump and controller are designed to work together reliably, so you can focus on enjoying your hobby rather than babysitting the top-off process.
Key features that simplify aquarium care
- Alarm-ready design with automatic alerts for empty bucket, leaks, stuck float, refill timeout, unplugged pump, or short circuit.
- Safe power usage at 12V, offering energy efficiency and reduced risk around water.
- Smart pause function lets you temporarily halt refills, then resume automatically after 30 minutes for flexible maintenance.
- Stable sensing with a precise water level sensor that minimizes overflow and remains reliable around plants or debris.
Real life use cases and practical benefits
- Saltwater tanks: steady top-offs help counter evaporation and support a calm, balanced environment for marine life.
- Hydroponic or mixed tanks: precise refill logic reduces the chance of overfills during routine maintenance.
- All-in-one convenience: replaces multiple floats and simplifies sump management for hobbyists and enthusiasts alike.
Setup is straightforward. The sensor, submersible pump, and controller install quickly, and the siphon joint should be in the replenishment bucket and above the water surface during operation. A durable PC stand helps keep the unit stable, and the compact design fits tanks up to 5/8 inch (16 mm) thick. The device is built for reliable performance even in presence of decorative plants or floating debris, thanks to anti-interference sensing and a robust construction.
