## Description

Compact, versatile auto top-off system with upgraded tech to automatically refill and maintain water levels in reef and planted aquariums of various sizes.

## Features

- Compact size - the entire optical sensor unit ONLY 0.8 inches diameter. The unit works on rimmed and rimless tanks, and as well as sump tanks. The whole machine is designed with quick-plug module, which is free of setup and super simple to install. The small size is not only beautiful, but also suitable for freshwater and seawater grass tanks of various sizes.
- New and Improved Features - Upgraded ETFT (Extended Time Filling Technology), AFT (Anti-fluctuation Technology), and QST 2.0 (Quick Security Technology). With all these new upgrades combined, our ATOs are far superior and safer. ETFT recognizes your tank size after it first initialized. Working alongside the ETFT, the AFT will be able to decide how long it takes to refill your tank without over-filling it when the QST alarm is triggered.
- QST 2.0 real-time monitoring - Prevents overfilling and pump dry run. The controller will give a visual alert and stop the pump immediately when it senses a refilling time more than 6 times longer than the time calculated by ETFT. QST can detect a malfunction of the sensor/controller or even an empty reservoir.In version 2.0 we incorporate ETFT feature and not relying on first filling time from version 1. Flooding barely happens when following the instructions carefully.
- Dual sensing optical probe-The dual precision optical sensors are 0.1 cm apart, which enables it to monitor the level fluctuation precisely (less than 0.6cm difference). The dual-sensing probe with excellent performance can operate in a completely dark environment, you could use it with confidence！
- Everything you need is included in the package - Powerful magnet supports 15mm thick glass wall. Check valve prevents water from back flowing from the tank. Hose holder allows you easily secure the tubing. Powerful 70gph water pump can lift water up to 2 m high.
- One-year warranty--Fzone will offer a one-year warranty, round-the-clock service, and you can reach out to us at any time for any product-related concerns.

## Questions & Answers

**Q: Any time the pump looses power and reboots when it gets power back does it have to refill all the way to top line for measurement? Or is it a one time**
A: Yes it has to refill to the top sensor so it can recycle, also if water level goes way below sensor when it reboots it will only pump 3 times then red light comes back on so unplug and plug back in so it can pump remainder water to reach level you might have to do this several times( i hope not) usually once is sufficient, hope this helps.

**Q: Can I use it on a 40 gal ?**
A: Yes, it will work fine.

**Q: Will this still work if I put a longer tube on it?**
A: Sure

**Q: How do you install hose clamp on a rimmed tank?**
A: Just rotate it. It will fit.
