Red Sea ReefDose 4

Automate reef supplementation with precision using the Red Sea ReefDose 4, a smart four-head dosing system engineered specifically for reef aquariums.

ReefDose combines four precision dosing heads, ReefBeat smart control, coordinated dosing schedules, multiple flow rates, and highly accurate delivery to automate calcium, alkalinity, magnesium, trace elements, and other compatible liquid supplements.

It's an especially strong match for Red Sea's 4-Part Complete Reef Care system, giving reef keepers four independently controlled channels in one compact dosing unit.

Four Precision Dosing Heads

ReefDose 4 features four independently controlled dosing heads designed for precise daily supplementation.

Each head can deliver from 0.2 mL to 1,000 mL per day, adjustable in increments of 0.1 mL.

Red Sea specifies accuracy of ±0.05 mL or an average deviation of 0.5% over a 10 mL dose, making the ReefDose suitable for reef systems where consistent supplementation matters.

Dynamic Dosing Queue

Instead of treating all four heads as completely separate timers, ReefDose uses Red Sea's Dynamic Dosing Queue to coordinate the day's dosing schedule.

The system automatically creates a combined schedule for all four heads and introduces delays between supplements to help prevent unwanted chemical interactions.

The queue also updates when dosing settings change and can reschedule doses missed due to events such as a power outage.

ReefBeat Smart Control

Connect ReefDose to the Red Sea ReefBeat app for programming and control from a compatible mobile device.

Create individual dosing schedules, configure automated dosing plans, perform manual doses, and manage the ReefDose alongside other connected Red Sea equipment within the ReefBeat ecosystem.

Three Dosing Speeds

Choose between three operating speeds depending on your dosing needs:

Whisper: 15 mL/min
Regular: 30 mL/min
Turbo: 45 mL/min

Whisper mode prioritizes quieter operation, while Turbo mode provides faster delivery when larger dosing volumes are required.

Easy Maintenance

The ReefDose dosing heads feature a click-on/click-off design, allowing the heads to be removed and installed without tools or manual alignment.

Secured tubing connectors are designed for flexible tubing with 5 mm outer diameter and 3 mm inner diameter.

Perfect for 4-Part Reef Supplementation

Four dosing heads make ReefDose 4 particularly well suited for multi-part supplementation programs.

Use individual channels for calcium, alkalinity, magnesium, trace elements, or compatible multi-part reef-care systems such as Red Sea Complete Reef Care 4-Part.
