Looking for a reliable reef doser? Reef Hacks takes a close look at the GHL Doser 2.1 in this detailed review.

GHL Doser 2.1 Slave, 4 Channel Dosing Pump - White

Keep your water values permanently stable: With GHL metering pumps the automatic addition of fluids is a breeze.

Dose trace elements, fertilizers, balling salts, or water, precisely to the milliliter. Programming is done by specifying the daily dose amount and the number of doses per day. Alternatively, you can also use timer functions if you wish to dose at specific times.

The high quality materials inside the doser ensure a long lifespan. If a pump needs to be replaced after many hours of operation, you can easily exchange it, thanks to the modular design.


The Right Model For Each Purpose.

The Doser Slave is available in versions with 2 to 4 pumps, pumps can be retrofitted at any time. Each pump can also be operated manually for easier replacement of liquids.

  • Doser without integrated controller (Slave Unit)
    • The device has an interface for connection to a ProfiLux Controller or to a Stand Alone Doser with integrated control electronics. If the Slave Doser is driven by a ProfiLux with level control, a pump can also be used for automatic level control or auto top-off.
