AutoAqua Smart ATO RO G2 | BRStv Product Spotlight
Keeping your ATO reservoir full is one of those reef tank maintenance tasks that seems simple enough—until you’re tired of carrying buckets, worried about forgetting to refill it, or trying to avoid the wasted DI resin that comes with constant small-batch RO/DI production.
That’s where the AutoAqua Smart ATO RO G2 comes in. It’s designed to automatically refill your ATO reservoir from your RO/DI system while helping prevent TDS creep, save DI resin, and add multiple layers of safety and redundancy to help protect against overfills.
With dual optical sensors, a DC solenoid valve, a backup float valve, safety alarms, and smart timer programming, the Smart ATO RO G2 gives reefers a much safer and smarter way to automate ATO reservoir refills.
What Does the AutoAqua Smart ATO RO G2 Do?
The Smart ATO RO G2 automates the process of refilling your ATO reservoir using water from your RO/DI system. Instead of topping off the reservoir every time the water level drops slightly, it allows the reservoir to drain down near empty before triggering a refill cycle.
That matters because frequent short RO/DI cycles can contribute to TDS creep, which sends higher-TDS water through your DI resin and can exhaust your resin more quickly. By waiting until the reservoir is low before refilling, the Smart ATO RO G2 helps reduce those repeated short production cycles and can help extend the life of your DI resin.
In other words, it is not just about convenience. It is also about making your RO/DI system run more efficiently.
How It Works
The Smart ATO RO G2 uses a pair of dual optical sensors inside your ATO reservoir. One sensor is placed near the bottom of the reservoir, and the other is placed near the desired fill line at the top.
The system also includes a DC solenoid valve that is installed in line with your RO/DI system. Depending on your setup, that valve can be installed either directly before the membrane if your RO/DI system does not have an auto shutoff, or after the RO/DI system before the ATO reservoir if your system does have an auto shutoff.
When the water level in the ATO reservoir drops low enough to trigger the bottom sensor, the controller opens the DC solenoid valve and allows your RO/DI system to begin filling the reservoir. Once the water reaches the upper sensor, the controller closes the valve and stops the flow of RO/DI water.
It is a simple process, but the advantage is in how controlled and redundant that process is.
Built-In Redundancy for Safer Automation
Automating water production can be intimidating because nobody wants to come home to a wet floor. The Smart ATO RO G2 addresses that concern with multiple layers of redundancy.
Each optical sensor is actually a dual sensor, which means each one has its own internal backup if one of the sensor elements should fail. The controller also includes built-in alarms and fill timers. After the first fill cycle, the controller learns how long it should normally take to refill your reservoir. If a future fill cycle takes much longer than expected, the system can automatically shut down to help prevent overfilling.
The included DC solenoid valve also adds another layer of protection. Because the valve requires power to open, it is most likely to fail in the closed position. That means a failure is less likely to result in uncontrolled water flow.
Finally, AutoAqua includes a float valve and mounting bracket for the reservoir. The float valve can be mounted to a vertical panel or horizontal brace and acts as a mechanical backup. If the solenoid were ever to fail open, the float valve can close and either trip the auto shutoff on your RO/DI system or at least dramatically limit the amount of water being produced.
Why It Helps Prevent TDS Creep
TDS creep happens when an RO/DI system starts producing water and the initial water coming from the membrane contains higher TDS than it does once the system has been running for a bit. If your reservoir is refilled in tiny amounts throughout the day, your RO/DI system may go through frequent start-stop cycles, exposing your DI resin to more of that higher-TDS startup water.
The Smart ATO RO G2 helps solve that by letting the reservoir drain much farther before starting a refill. Instead of making a little water over and over, it produces a larger batch less frequently. That helps reduce how often your DI resin is exposed to startup TDS creep and can help stretch the life of your resin.
Easy Installation and Clear Instructions
One of the standout details with the Smart ATO RO G2 is the manual. AutoAqua did a great job with large color diagrams that clearly show where each component goes and how the system should be installed.
That makes setup much easier, especially because this device includes several different safety features, sensors, and installation options. The manual also explains how the alarms, timers, and redundancies work, so you can understand what the controller is doing instead of just plugging it in and hoping for the best.
Who Is the Smart ATO RO G2 Best For?
The AutoAqua Smart ATO RO G2 is a great option for reefers who want to automate ATO reservoir refills without relying on a basic float valve alone. It is especially useful if you already have an RO/DI system near your tank or mixing station and want a safer way to keep your reservoir topped off automatically.
It is also a strong choice for reefers who want to reduce TDS creep, save DI resin, and build more redundancy into their water production setup. If you like the idea of doing less bucket hauling while still keeping safety at the front of the design, this is exactly the kind of device worth considering.
