Red Sea ReefDose 4

Red Sea ReefDose 4 automates daily supplementation for reef aquariums with patent-pending single-drop accuracy (±0.05ml). The advanced controller's Dynamic Dosing Queue intelligently coordinates all four heads into one seamless schedule, automatically rescheduling missed doses after power outages. Control via the ReefBeat App with four easy-set dosing modes—choose Whisper (15ml/min) for silent operation, Regular (30ml/min), or Turbo (45ml/min) for speed. Dosing range spans 0.2ml to 1000ml per head in 0.1ml increments. Tool-free click-on/off heads, automatic inter-head delays to prevent chemical reactions, and on-demand manual dosing round out the feature set. Integrates seamlessly with the ReefBeat smart ecosystem. Motor rated for 10 years at 250ml/day per head. Dimensions: 8.9" × 4.1".
