In reefkeeping, real protection isn't about complex settings or loud alarms—It's about peace of mind you don't have to think twice about.
Protection that's quiet. Constant. And always there when you need it.

Unusual drain times, endless top-offs, pumps running dry—those “what's going on?ˮ moments are something every reefkeeper has faced.
That's exactly why we developed QST (Quick Security Technology):
a built-in safety guard that works in the background, silently watching over your tank and stepping in when something's off—so you don't have to. And the best part? It requires no extra setup. It's automatic, intuitive, and always on duty.

● What is QST?

Quick Security Technology (QST) is AUTOAQUA’s built-in, automatic safety system that protects your aquarium during daily ATO and AWC operations. There's no setup required. It works in real time—monitoring your pump's behavior and stepping in when something isn't right.

QST helps prevent common problems such as:
✦ Overfilling
✦ Dry running pumps
✦ Empty reservoirs
✦ Sensor or pump malfunction

By detecting abnormal pump behavior, QST will shut down the system and alert you—before a small problem turns into a major issue.
It‘s a smart, silent layer of protection that works in the background—so your aquarium stays safe, and your attention stays on the reef, not the equipment.

● How Does QST Work?

Think of QST as a built-in smart timer — learning how your system behaves from the very first time it runs.
During setup, it records how long your pump normally takes to refill or drain—and then uses that time as a reference to spot problems later on.

For example, a small nano tank might only need 3 seconds to refill, while a larger system could take 20 seconds or more.
QST quietly records this first operation and uses it as the benchmark for what's “normalˮ in your setup.

From that moment on, QST watches for anything out of the ordinary.
If a refill takes six times longer, or a drain runs three times past the usual time, QST immediately steps in to stop the process and protect your system—before a small issue becomes a big problem.

That's the power of QST:
It doesn't guess. It learns.
Then it safeguards—based on your unique system, not a fixed rule.

Whether your setup is compact or complex, QST adapts and responds in real time, delivering reliable protection that works quietly in the background—so you can focus on enjoying your reef, not worrying about what might go wrong.

In both cases, QST uses a combination of LED indicators and audible alerts to inform you of any detected abnormality. It's smart, automatic, and always on.

● Why Does the First Operation Time Matter?

Because QST uses your device's first operation as the baseline to define what's “normalˮ. To give QST a solid start, make sure your system is running smoothly during its first use. For example:
✦ The reservoir is properly filled
✦ Tubing is not blocked, tangled
✦ The pump and sensor are installed correctly and securely

If your initial refill takes too long—maybe because of tangled tubing or a low water level of reservoir—QST will treat that as the normal runtime.
As a result, it might delay triggering an alert in real emergencies like overfilling or dry pump situations.

Teach it once. Trust it always.
A clean and correct setup helps QST perform accurately and reliably over time.

● QST is Built into These Models

AUTOAQUAʼs goal is simple: Smarter automation, safer aquariums. With QST, the tank stays protected—quietly, efficiently, and automatically.

● QST: The Calm Behind the Scenes

With QST quietly watching your system, you can finally stop worrying—and just enjoy your reef.

QST isn't just a feature.
It's a built-in layer of protection that makes reefkeeping simpler, safer, and more relaxing.
It monitors your system in real time, steps in when something feels off, and lets you know—before a small issue becomes a serious one.

For the most accurate protection, always set up your system under stable, proper conditions.
That first operation teaches QST what “normalˮ looks like—so it can recognize the moment things aren’t.

Teach it once. Trust it always.
Whether you're away on a weekend trip or asleep at night, QST is always there—silently keeping watch.
You may never notice it working. And that's exactly the point.
Because the best kind of protection doesn't interrupt—it simply works.
Quietly. Confidently. Every single day.
