Red Sea ReefDose 2

The Red Sea ReefDose 2 is a two-head smart dosing pump for automated aquarium supplementation, combining single-drop dosing accuracy, ReefBeat app control and coordinated daily scheduling for reef, marine and freshwater dosing routines.

Two-Head Smart Dosing for Aquarium Supplements

ReefDose 2 is ideal when the aquarium needs reliable automation for two liquid supplements, such as two-part dosing, trace elements, nitrate/phosphate control or liquid foods where controlled delivery matters. The compact two-head format is easy to place in a cabinet, mount on a vertical surface or integrate with other ReefBeat-connected Red Sea devices.

Red Sea ReefDose 2 Features

• Two independent dosing heads: Supports two separate liquid supplements with individual head setup, priming and calibration.
• Single-drop dosing accuracy: Direct-drive planetary gear-motor heads are rated by Red Sea to +/-0.05 ml accuracy.
• Dynamic Dosing Queue: Combines all head schedules into one coordinated daily plan and can reschedule missed doses after interruptions such as power outages.
• Four automatic dosing programs: Supports single daily dose, 24 hourly doses, timer schedule and customized schedules with multiple time periods.
• Flexible daily dose range: Each head can dose 0.2-1000 ml per day in 0.1 ml increments.
• Three flow rates: Selectable 15, 30 and 45 ml/min dosing speeds allow a quieter or faster dosing approach depending on the application.
• ReefBeat App control: Provides scheduling, dose logs, manual dosing, supplement volume monitoring and connected-device integration.
• Tool-free head handling: Click-on/click-off dosing heads simplify head installation and servicing.
• Flexible mounting options: Wall mounting bracket is included and the device can also be placed on a flat surface when tubing is not restricted.

Application and Compatibility Notes

Use the Red Sea ReefDose 2 when two dosing channels are enough for the aquarium's supplementation plan. For full multi-part dosing, larger supplement programs or four separate liquids from a single device, the Red Sea ReefDose 4 is the more complete option. Calibration is required for each head and should be repeated when changing supplements or replacing internal dosing tubes.

Setup Directions

Mount the ReefDose 2 securely inside the aquarium cabinet or place it on a stable flat surface where tubing will not kink or be pulled. Connect the inlet tube from each supplement container to the left hose barb of the matching head and route the outlet tube from the right hose barb to a secure dosing point above the sump. Prime each line, onboard the device in ReefBeat, then calibrate every head with the measuring cylinder before activating an automatic schedule. Recalibrate whenever changing supplement type or replacing the internal dosing tube.
