Red Sea Complete Reef Care 4-Part – Large

Simplify reef supplementation with the Red Sea Complete Reef Care 4-Part Dosing System, an all-in-one supplementation program designed to provide the major, minor, and trace elements corals need for healthy growth and vibrant coloration.

The Complete Reef Care program combines Red Sea's foundation and trace-element supplementation into just four bottles, providing 36 essential elements in biologically balanced ratios.

This Large system is designed for reef aquariums up to 160 gallons (600 liters) and is ideal for established reef systems looking for a streamlined approach to ongoing coral supplementation.

Complete Reef Care in Four Parts

The system combines the essential elements required by corals into four coordinated supplements.

Part 1 – Calcium & Magnesium

Supports coral skeletal development and replenishes key foundation elements consumed as corals grow.

Part 2 – Alkalinity & Potassium

Supports stable carbonate hardness while replenishing potassium and other elements required by growing corals.

Part 3 – Iron & Trace Elements

Provides iron and additional trace elements associated with coral biological processes and pigmentation.

Part 4 – Trace Elements

Completes the supplementation program with additional minor and trace elements needed by the reef ecosystem.

Together, the four supplements replenish 36 major, minor, and trace elements according to Red Sea's Complete Reef Care program.

One Test Guides Your Dosing

One of the coolest features of Complete Reef Care is its simplified dosing approach.

Instead of independently testing and calculating the consumption of dozens of individual elements, Red Sea's system uses calcium consumption as an indicator of coral growth and overall element consumption.

Once your aquarium's calcium demand is established, all four parts can be dosed according to Red Sea's recommended ratios.

That means routine management of the complete supplementation program can be based around one weekly calcium test.

Designed for Automated Dosing

Complete Reef Care is an excellent companion for multi-channel dosing pumps, including the Red Sea ReefDose, allowing all four supplements to be administered consistently throughout the week.

Automated dosing can help maintain more stable parameters while reducing the need for frequent manual supplementation.
