🐠 Advanced Dual-Sensor XP Aqua Duetto Auto Top Off ATO for Complete Aquarium Maintenance Review

This thing is amazing. It's so compact and easy to install. I installed it in 30 minutes including the time it took to drill and run a hose through my "reservoir" to get it as clean as possible. The sensors are very sensitive to the water level, which is great as the failsafe stops at any moment. It's also great that there are audible warnings when the tank is empty, clogged etc. Of course it also has a feature that detects when the pump is running too long and shuts it off. The hose is nice…

This ATO worked perfectly, exactly 6 months, then it just stopped working. The controller is dead. At first XP Aqua claimed it must be the PSU but it wasn't, I told them I had checked and it was fine, it was the controller. They sent the power supply, the problem is not in it. Now they said they would only replace it if I sent it back to them because I must have dropped it in the tank or connected a different power supply. Both are not possible. So I have to spend the time and money to send it…

I've only had this 1 week but I already like it. I have a 10 gallon reservoir tank and this system is in my 90 gallon frag tank. It took about 5 minutes to install and connect. It attaches well to a stand or wall with screws (not included), perhaps a strong velcro will suffice. There's an alarm clock on it. If a problem is detected, an alarm will sound. I turned it off once and it was due to air bubbles forming on the sensor. Cleaned up and he went right back to work. I'm afraid the mount won't

This auto topping certainly gets the job done. I managed to keep the water parameters much more stable and never had a single problem with the sensor. It reads very accurately and has never failed. There is one thing I don't like about this auto-refill though. For example; When I turn on supply mode on my pumps, it is obvious that the sump is filling with water. The ATO is obviously registering a water level well above the "working" level as the blue LED ring on the control module will flash…
