• Up to 4,600 L/h — continuously adjustable from the controller or the Aqua Medic App, rather than a single fixed speed.
• Low power draw — 3–15 W depending on the flow setting, run off a 24V DC pump head powered through the included 100–240V transformer, which accepts Australian 230V/50Hz mains.
• Magnetic mount — holds through glass up to 10mm thick, so the pump body sits inside the tank with no visible bracket outside it.
• Fully submersible — rated IP X8.
• App and controller control — set constant flow, pulse, ramp, or random wave patterns from the Aqua Medic App, or drive it from the included physical controller.
• Multi-pump sync — pair two or more Smart Drift units for master–slave or cross-flow patterns across a wider tank.
• Feed pause — a one-touch pause on the controller stops flow during feeding, so food doesn't get blasted into the overflow before your fish find it.

Aqua Medic's own operation manual for the Smart Drift 3.1 states the flow is continuously adjustable between 30% and 100% of the rated 4,600 L/h maximum — so from roughly 1,400 L/h up to the full 4,600 L/h, depending on the pattern and setting you choose from the controller or app. This is the manufacturer's documented control range rather than a single headline number, and it's what lets you run a gentle random wave for a planted tank one week and a strong constant flow for a reef the next.

The three models are physically different pump sizes, not the same body at different power settings — moving up a size means a larger pump head and a thicker maximum glass rating, not just a firmware change. For a nano or standard display tank up to around 300 L, the 3.1 is the right starting point; a larger reef or a tank over 300 L will outgrow its flow range.

Suitable for freshwater and marine tanks up to roughly 300 L that want app-controlled, patterned flow rather than a single fixed-speed powerhead. Not intended for glass over 10mm thick — the magnetic mount won't hold reliably beyond that, so check your tank's glass or acrylic thickness before ordering.

Pair with a second Smart Drift 3.1 for cross-flow in a wider tank, or step up to the 7.1 if you're planning a larger system later — the app supports mixed-model multi-pump sync.

Can I run the Smart Drift 3.1 without the app?

Yes. The included physical controller runs the pump and its flow patterns without needing a phone connected — the app adds remote control and additional pattern options.

What's the minimum flow it can run at?

Aqua Medic's manual for this model documents a continuously adjustable range down to 30% of the rated maximum, so approximately 1,400 L/h at the low end.

Will it fit a rimless nano tank?

It mounts magnetically through glass up to 10mm thick, which covers the great majority of nano and standard display tanks — check your glass thickness if you're unsure.

Does it have a feeding mode?

Yes — a one-touch feed pause on the controller stops the flow for feeding, then resumes automatically.

Is it fully submersible?

Yes — Aqua Medic rates the 3.1 at IP X8.
