Red Sea ReefDose 2 Dosing Pump


For daily supplementing reef aquariums

Red Sea’s highly-anticipated ReefDose redefines ease-of-use and smart functionality for aquarium dosing pumps, offering advanced programming and incredible dosing accuracy for the most demanding applications. The ReefDose was built from the ground up to meet the needs of modern reef aquarists. Utilizing Red Sea’s custom-built dosing heads, the ReefDose is capable of delivering incredible single-drop precision through a variety of dosing programs. The three dosing speed settings offer additional versatility, prioritizing whisper quiet operating at up to 15mL per minute, all the way up to 45mL per minute with Turbo mode.  



  • Single drop accuracy dosing heads with a direct-drive planetary gear-motor, provides an accuracy of ± 0.05ml or an average deviation of 0.5% (over 10ml).
  • 4 easy-set, smart dosing options for each head, that are automatically combined into one coordinated schedule.
  • Easy assembly click-on/off dosing heads (no tools or alignment required).
  • Automatic delay between the heads to prevent chemical interaction between supplements.
  • Automatic dose compensation for doses missing due to power loss.
  • Daily dose per head of 0.2ml up to 1000ml in increments of 0.1ml.
  • On-demand manual dosing.
  • 3 dosing flow rates: Whisper 15ml/min, Regular 30ml/min, Turbo 45 ml/min.
  • Motor life expectancy of 10 years – based on 250ml/day/head. 

The ReefDose is more than just another programmable dosing pump. Smart software functionality like the “Dynamic Dosing Queue” run by the controller combines the desired dosing plans for each head into one coordinated daily dosing schedule for the complete device. The queue is automatically updated after any settings changes, and reschedules any doses that are missed due to unscheduled events such as power outages, maintenance, or feeding.
