ReefDose 4

Smart 2- or 4-channel Wi-Fi dosing pump for marine reefs. The manufacturer states an approximate single-drop accuracy of ±0.05 ml, three flow speeds, a user-configured dynamic dosing queue, Food Head mode, and ReefBeat control.

The Red Sea ReefDose (available in the 2-channel ReefDose 2 and 4-channel ReefDose 4 versions) is an app-controlled peristaltic dosing system for marine reef aquariums that require repeatable liquid-supplement schedules.

The primary target includes:

• SPS/LPS Coral Reef Aquariums: Systems with regular Calcium, Alkalinity (KH), or Magnesium demand, where a user-determined daily amount can be divided into smaller additions. The correct amount still depends on aquarium testing and the supplement instructions.
• Trace Element Supplementation: Liquid supplements can be scheduled in the amount selected by the aquarist, within the product's declared dosing range.
• Liquid Coral Food or Nutrient Programs: A head can be designated as a Food Head so that dosing triggers Feed Mode for compatible devices that the user has configured in ReefBeat.

Who It Is NOT For:

• Low-Tech or FOWLR (Fish-Only) Aquariums: Systems without stony corals having negligible chemical consumption.
• Installations Without 2.4 GHz Wi-Fi: Environments lacking standard 802.11 b/g/n wireless networks.

The architecture of the Red Sea ReefDose employs peristaltic heads driven by bespoke planetary gear stepping motors, ensuring micro-step angular control without the inertial coasting of traditional DC motors.

• Single-Drop Precision (0.05 ml): Planetary gear transmission allows the delivery of single 0.05 ml drops (as slow as 1 drop every 15–30 seconds).
• Three Operational Speeds:
• Whisper (15 ml/min).
• Regular (30 ml/min): Balanced standard speed for daily dosing schedules.
• Turbo (45 ml/min): High speed for manual top-ups, priming, and liquid coral feeding.
• Dynamic Dosing Queue: ReefBeat places scheduled doses in a queue and respects the delay between heads configured by the user. This can reduce simultaneous delivery, but it does not determine chemical compatibility.
• Missed Dose Compensation: When normal operation resumes, doses missed earlier that day are rescheduled as soon as possible. Any amount not delivered before midnight is cancelled; the feature is configured per head.
• "Food Head" Mode: Assigning a dosing head as a Food Head triggers ReefBeat Feed Mode for the compatible devices selected by the user.

Anti-Precipitation Chemical Dynamics. Simultaneous dosing of concentrated Calcium and Alkalinity solutions causes the precipitation of insoluble calcium carbonate:

This reaction (carbonate snow) can remove dissolved material from the water. The ReefBeat Dynamic Dosing Queue respects the delay between heads configured by the user and can reduce simultaneous delivery. The aquarist remains responsible for separating outlets and choosing an appropriate delay.

ReefBeat Ecosystem Integration.

• Feed Mode Trigger: In Food Head mode, dosing can trigger Feed Mode for compatible ReefBeat devices that the user has configured.
• Volume Monitoring: Real-time tracking of remaining volume in supplement containers (500 ml, 1000 ml, or custom) with proactive refill alerts.

Step-by-Step Guide.

• Mounting: Secure the mounting bracket with built-in bubble level inside the dry cabinet and slide the unit onto the mount.
• Tubing Connection: Push 3/5 mm TPE lines into the quick-connect Click-Fit head barbs until locked.
• Wi-Fi Pairing: Connect the device via the ReefBeat app over a standard 2.4 GHz wireless network.
• Priming: Press and hold the prime button in the app until the line is completely filled and the first drop appears at the tip.
• 4.0 ml Calibration: Position the dosing tip over a 10 ml graduated cylinder, run the calibration cycle, verify that the dispensed volume is between 3.95 ml and 4.05 ml, and confirm the value in the app.

• External Cleaning: Periodically wipe external surfaces to remove moisture and salt deposits; do not immerse the unit.
• Recalibration: Calibrate at first use, when changing to a different supplement, and after replacing an internal dosing tube.
• Internal Dosing Tube: The manual indicates replacement approximately once per year, using the original dosing-head tube assembly.
• Backup Battery: Replace the 3 V CR1220 backup battery every few years, following the manual procedure.

Advantages.

• Stated Single-Drop Accuracy (approximately ±0.05 ml): Planetary gear stepper motors support small scheduled additions within the declared operating range.
• Dynamic Queue: Respects the delay between heads configured by the user and can reduce overlapping delivery.
• Feed Mode Integration: A Food Head can trigger Feed Mode for compatible devices selected in ReefBeat.
• Same-Day Missed Doses: Missed doses are rescheduled as soon as possible when normal operation resumes; undelivered amounts are cancelled at midnight.
• Quick-Release Heads: Tool-free head swap in seconds.
• Three Flow Speeds: Whisper (15 ml/min), Regular (30 ml/min), and Turbo (45 ml/min) modes.

Operating Limitations.

• Accessories Sold Separately: Colored tubing, sump tube holder, and cylinder are optional (Deluxe Tubing Kit).
• 2.4 GHz Wi-Fi Requirement: Requires 2.4 GHz Wi-Fi during initial setup.
• App UI Step Resolution 0.1 ml: While physical dispensing is 0.05 ml, app inputs round to 0.1 ml increments.
• Premium Price Point: Higher investment than entry-level DC motor dosing pumps.
