Red Sea - Complete Reef Care

Red Sea Complete 4-part Reef Care Program is a comprehensive reef care maintenance program for your saltwater aquarium with many corals. This makes the maintenance and testing of a marine aquarium much faster. All you need to do is measure your Calcium (Ca) and occasionally check your alkalinity (kH) for a double check to ensure the values remain balanced.


You have a beautiful saltwater aquarium and want to keep it that way. With the four-part Red Sea RCP (Reef Care Program), you have the solution to promote the growth and color of your corals, save costs, and make your aquarium maintenance more routine. After extensive research, Red Sea has demonstrated that in most reef systems and marine aquariums without a refugium, the levels of Major, Minor, and Trace elements, as well as the Alkalinity components, are consumed in a relatively constant ratio. Since calcium is a crucial component for coral growth, the four-part program focuses on performing a weekly calcium measurement, which determines the dosages for all four parts of the kit.

What is in the box?

The new Complete Reef Care program is available in 3 sizes, so whether you have a small mixed reef or a large SPS system, Complete Reef Care has a solution for you. If you connect the 4 parts to your Red Sea ReefDose, dosing supplements becomes even easier.

Ten years ago, I started setting up a freshwater aquarium. Since then, I always have been fascinated by the underwater world. Together with my wife, we have been fortunate to discover this on many beautiful journeys and explored the magnificent underwater world through diving. In 2023, we have started a 60-liter saltwater aquarium. Soon, we realized that we wanted to further expand our saltwater aquarium hobby, so we switched to a Red Sea Peninsula 650. It's a fantastic aquarium that brings daily joy to me, my wife, and our daughter. I enjoy keeping up with the latest developments in the saltwater world and love exploring how to make my tank even smarter and easier to maintain. As a newcome, I would like to share all my experiences in setting up a saltwater aquarium with you!

Salt has always run in my blood. From birth, aquariums surrounded me, first at my grandfather's and later at my parents’ place. Now, at the age of 30, I've been able to set up my dream tank, a 160x70x70 peninsula. Corals hold the second spot for me; fish and the entire ecosystem are the reasons I have an aquarium. Nearly a decade ago, I started with my first aquarium, making plenty of mistakes and learning a great deal from them. Since 2021, I've been working at Ocean&Lake in the Netherlands, where I am now fully responsible for the saltwater department.
