Red Sea ReefDose 4

The Red Sea ReefDose 4 is a four-head smart dosing pump for advanced aquarium supplementation, giving reef keepers precise app-controlled dosing for complete multi-part programs, trace elements, nutrient control liquids and other regularly dosed aquarium supplements.

Four-Channel Dosing for Complete Reef Programs

ReefDose 4 is the stronger choice when one device needs to manage four separate liquids with accurate, repeatable dosing. It is especially well suited to Red Sea's multi-part reef care approach, larger reef aquariums, SPS-dominant systems or any aquarium where several supplements need coordinated daily delivery without manual measuring.

Red Sea ReefDose 4 Features

• Four independent dosing heads: Manages up to four separate supplements from one connected dosing unit.
• Single-drop dosing accuracy: Bespoke direct-drive dosing heads are rated by Red Sea to +/-0.05 ml accuracy.
• Dynamic Dosing Queue: Coordinates all dosing heads into one daily queue and automatically updates the schedule after setting changes or missed doses.
• Four smart dosing programs: Supports single daily dose, 24 hourly doses, timer schedule and customized dosing windows for each head.
• Wide dose range: Each head supports 0.2-1000 ml per day in precise 0.1 ml increments.
• Selectable dosing speeds: 15, 30 and 45 ml/min flow rates allow quieter low-speed operation or faster dosing when appropriate.
• ReefBeat integration: Provides app scheduling, manual dosing, dose logs, supplement volume monitoring, missed dose notifications and connected Red Sea device control.
• 4-Part Reef Care ready: Designed to simplify complete Red Sea reef care dosing when paired with the appropriate Red Sea supplement program.
• Cabinet-friendly installation: Includes a wall mounting bracket and uses secured connectors for flexible dosing tubing.

Application and Compatibility Notes

Use the Red Sea ReefDose 4 when the aquarium needs more than two automated dosing channels or when running a complete four-part supplementation plan from one device. Each head should be individually primed and calibrated for the specific supplement being used, since liquid viscosity and tubing condition affect dosing accuracy.

Setup Directions

Mount the ReefDose 4 in a dry cabinet area away from direct splash and open water, or place it on a stable flat surface with unobstructed tubing paths. Connect each supplement container to the left inlet barb of its assigned head and route the outlet tubing from the right barb to a secure dosing point above the sump. Prime each channel, connect the unit to ReefBeat, calibrate all four heads with the measuring cylinder and confirm the dosing queue before enabling automatic operation. Recalibrate after changing supplements or replacing head tubing.
