XP Aqua Ultimate ATO - Complete 4-Sensor Aquarium Auto-Top-Off System
Why Choose Ultimate ATO?
With 2 X dual-optical sensors, the Ultimate ATO is the first ATO to include 4 sensors. The 4 sensors allow us to design a dual-stage overfill alarm that is less intrusive as well as a run-dry protection feature that prevents your sump from running dry: which is also a first. The Ultimate ATO’s versatility is also unmatched. An efficient DC pump is included for a standard installation. If you require a larger ATO pump for a remote sump installation, a Socket Switch is included that allows you to run a pump up to 10A (1000W). A solenoid valve is also included for aquariums that are topped off directly with an RO/DI system. We designed the Ultimate ATO to offer you the ultimate protection with the ultimate convenience!

Fails
Cons: Fails on on position
Worked well for a few months then I came home to an overfill tank. Thought maybe another piece of equipment was interfering with the sensor so I moved the other piece. Worked well for a week then came home to an overfill tank again. The control unit is not stopping the pump even though the alarm is sounding. Going in the trash. Now have to buy a new ato

Was impressed, but now I'm not so sure!
Pros: Small and easy set up
Cons: No live customer support, just an e-mail
Bought this almost a year ago and it stopped working. It's placed in a secure location away from the sump and all other components and it has a burnt smell. When I have issues I expect help and XPAqua has no live support or 800 number to call and speak to someone. To me as a consumer in this hobby that is very important! I 'll be sending it in hopefully for warranty exchange, but next time I'll check support availability before I buy in combination with product rep.

Super easy
Pros: Super easy setup
Super easy setup, less than 10 minutes. Dc pump stopped working after a day, but great communication with manufacturer, immediately sending me a replacement. Use the "switch" with a ppwerhead in the meantime and works great.

Great ATO
Pros: Easy to Use and Set Up, 4 Sensors, Looks good, Touch sensor button on control
Cons: None so far, no wifi text message for when my ATO bucket is low
I set this up on my tank in literally 10 minutes from start to finish. Very simple to use design and so far the sensors have done there job well. Theres a small tone when theres too much water added. (I learned from me adding water separately to see what happened, not the ATO malfunctioning). The pump it comes with is Tiny but seems to be powerful enough. It comes with an attachment to allow you to add your own pump but I would definitely give the little one a try, it may surprise you. Its got literally one button thats function is easily explained in the instructions manual (Touch sensor with a Boop sound). I plan on buying one for my other tank that's currently ATO-less. (My 3rd tanks has the Tunze osmolator ATO and this one is much easier to understand and set up in comparison) (Instagram: Raiders_Reef)
