AutoAqua Magnetic Stir Bar
The 3 x 7 mm bar that keeps a dosing container mixed.
The AutoAqua Magnetic Stir Bar (SB-0307) is the spinning element for the AutoAqua Smart Stir. It drops into a dosing container and the Smart Stir's magnetic drive turns it from outside the bottle, keeping supplements that settle out – carbonate powders, amino blends, phytoplankton – evenly suspended. The dose your pump draws from the bottom of the bottle then matches the dose it drew when the bottle was full.
What it fits
AutoAqua lists the SB-0307 as an accessory for the Smart Stir. At 3 mm across and 7 mm long it is sized for the small dosing containers the Smart Stir is built around, not for a mixing drum or a laboratory flask.
Key features
- 3 x 7 mm – small enough to pass through a dosing container's neck and to couple with the Smart Stir's drive.
- Corrosion-resistant construction – AutoAqua specifies a corrosion-resistant material for permanent immersion, though it does not name the polymer.
- Driven through the container wall – nothing passes through the lid, so there is no shaft, no seal and nothing to leak.
- No wearing parts – the bar is the whole mechanism; if it spins freely it is working.

Suitable for, and not suitable for
Suitable for:
- AutoAqua Smart Stir dosing containers
- Freshwater and marine dosing systems
- Supplements that settle or separate between doses
Not suitable for:
- Large reservoirs or mixing drums – the bar is sized for small dosing containers
- Use on its own – it needs a magnetic stirrer such as the Smart Stir to drive it
Care and maintenance
Rinse the bar in RO water whenever you refill or change supplement, so residue does not build up and put it out of balance. If dosing accuracy drifts, check the bar is still turning freely rather than sitting stalled against the container wall.
Goes well with
- AutoAqua Smart Stir – the drive unit this bar belongs to
- Red Sea ReefDose 4 – the doser drawing from the container being stirred
- Red Sea Reef Care Calcium+ Foundation A (Powder) – the kind of made-up supplement that settles between doses
- Controllers, dosing and automation
- The full AutoAqua range

Common questions
Which AutoAqua unit does this stir bar belong to?
The AutoAqua Magnetic Stir Bar is listed by AutoAqua as an accessory for the Smart Stir, which provides the magnetic drive that turns it.
Why does a dosing container need stirring at all?
Made-up powders and suspensions settle. Once they do, the doser draws a weaker solution from a container that has been standing than from one just mixed, so the delivered dose changes without anything on the pump changing.
What is the stir bar made of?
AutoAqua describes it as a durable, corrosion-resistant material suited to long-term aquarium use, but does not publish the specific polymer.
How do I clean it?
Rinse it in RO water at each supplement change. Avoid detergents, which are difficult to rinse fully out of a dosing container and end up in the tank.
