Red Sea Complete Reef Care – 4-Part Supplement Program

Red Sea Complete Reef Care is a simplified four-part dosing program designed to provide reef aquariums with all 36 major, minor and trace elements regularly consumed by corals.

Instead of separately dosing multiple Foundation and Trace-Colors supplements, the Complete Reef Care system combines the required elements into four balanced solutions. The program is based around your aquarium’s calcium consumption, allowing all four supplements to be adjusted together using a single weekly calcium test.

Designed primarily for reef aquariums without a refugium, the system supports coral growth, skeletal development, coloration and stable reef chemistry while making regular supplementation much easier to manage.

The 4-Part System

Part 1 – Calcium & Magnesium+
Provides calcium, magnesium, strontium and barium to support coral skeletal growth and calcification.

Part 2 – KH/Alkalinity & pH Stabilizer
Provides the carbonate and alkalinity components required for coral skeletal formation while helping maintain stable alkalinity and pH.

Part 3 – Iodine & Potassium+
Provides potassium, boron and the halogens iodine, bromine and fluorine, supporting coral pigmentation and biological processes.

Part 4 – Iron & Bioactive Elements
Provides iron, manganese, cobalt, copper, aluminium, zinc, chromium, nickel and additional bioactive trace elements involved in coral coloration and metabolic processes.

Key Features

• Complete four-part reef supplementation system

• Replenishes 36 major, minor and trace elements

• Supports coral growth and coloration

• Suitable for SPS, LPS and soft coral reef aquariums

• Dosing is based on measured calcium consumption

• Only one calcium test per week is required once the system is established

• Maintains calcium, magnesium, alkalinity and essential trace elements together

• Fixed dosing ratio simplifies reef maintenance

• Suitable for manual dosing or automatic dosing pumps

• Integrates with Red Sea ReefDose and ReefBeat

• Designed primarily for reef systems without a refugium

How the Dosing Ratio Works

The four solutions are formulated to be dosed in a fixed ratio based on Part 1.

For every:

5mL of Part 1

Dose:

• 10mL Part 2

• 2.5mL Part 3

• 2.5mL Part 4

Once your aquarium’s calcium consumption has been established, adjust the amount of Part 1 and maintain the same ratio across Parts 2, 3 and 4.

For example, if calcium consumption increases and Part 1 needs to be increased, the other three parts should also be increased proportionally.

How to Use

Start by establishing the recommended calcium level for your reef aquarium.

Test calcium and determine your aquarium's daily calcium consumption. Set the daily dose of Part 1 according to this consumption, then dose Parts 2, 3 and 4 according to the fixed ratio.

Continue testing calcium approximately once per week. If calcium begins to rise or fall from the target level, adjust the daily dose of Part 1 and adjust the remaining three parts proportionally.

For automatic dosing, the four supplements can be connected to a four-head dosing system such as Red Sea ReefDose 4.

Important

The Complete Reef Care 4-Part Program is designed to be used as a complete system, with all four parts dosed in the correct ratio.

For reef aquariums operating with a refugium, Red Sea recommends its traditional 7-Part Foundation and Trace-Colors program instead, as this allows individual element groups to be adjusted more precisely for the requirements of both the corals and refugium.
