Bubble Magus Kalkwasser Stirrer Motor

If the motor on your kalkwasser reactor has worn out or slowed down, this genuine replacement motor brings your system back to life. Designed for use with Bubble Magus kalkwasser reactors (e.g. KA100 / KA150), this motor gently and continuously mixes kalkwasser — producing a stable, saturated lime‑water solution for your reef tank.

What it does:

• Keeps the kalkwasser slurry properly stirred so only fully dissolved solution drains into your tank.

• Maintains consistent saturation — no clumping or uneven dosing.

• Works quietly and reliably (when used intermittently, not 24/7).

Why you might need it:

• Original motor slows down or fails after prolonged use.

• To extend the lifespan of your kalkwasser reactor without buying a brand‑new unit.

• For maintenance purposes: motors exposed to high‑pH kalkwasser solutions wear out over time; replacing the motor renews performance.

⚠️ Important Notes / Cautions

• Designed for use with kalkwasser reactor systems — not a general aquarium pump.

• Use only with freshwater (RO/DI) and correct kalkwasser powder; handle calcium hydroxide powder carefully (wear gloves / avoid inhaling dust). 

• Do not run continuously 24/7 (many users and sellers recommend short, periodic stirring for safety and motor longevity). 

• Ensure proper ventilation and setup so kalkwasser solution drains by gravity, not pressure (to avoid risk, damage or safety issues).
