Meet the new 4-piece Complete Reef Care that offers hobbyists more convenience at no extra cost and ensures optimal coral growth and vibrant colors with just one test per week!
Our long-term research has shown that in most reef systems without a refugium, the major, minor and trace elements and even the alkalinity components are consumed in a relatively fixed ratio.

Since calcium is the key indicator of coral growth, the 4-part program revolves around a single weekly measurement of calcium that determines the dosage of all 4 parts.

The new Complete Reef Care is available in 3 sizes to suit all system sizes. It is formulated so that all 4 parts are consumed at the same time and when supplemented with Red Sea's ReefDose, the hobbyist only needs to set their calcium dose and the ReefDose does the rest, which is super convenient. 

The new Complete Reef Care is chemically identical to our original 7-part program and delivers the same great results. However, systems with refugiums should use Red Sea's 7-part RCP to properly care for all elements.
