Red Sea 4 Part RCP Reef Care Program - Med 80 gal.

Red Sea 4 Part RCP - Med 80 gal.

Red Sea's long-term research has revealed that in most reef systems without a refugium, the Major, Minor, and Trace elements and even the Alkalinity components are used up 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, which determines the dosages of all 4 parts. 

The new Complete Reef Care is available in 3 sizes, to fit all system sizes. It is formulated so all 4 parts are used up at the same time, and if supplemented via Red Sea’s ReefDose, the hobbyist needs only to set their Calcium dose and ReefDose does the rest, which is super convenient.

The new Complete Reef Care is chemically identical to our original 7-part program and provides the same great results, however, systems with refugium should use Red Sea’s 7-part RCP to properly maintain all elements.
