4-Part RCP Complete Reef Care Dosing System

As Simple as 4 Bottles and 1 Test Per Week 36 Major, Minor, and Trace Elements Pairs Seamlessly with ReefDose 4 Dosing Pump Three Sizes Available to Match Your Tank Size The new Complete Reef Care is based on Red Sea's 30 years of research into the needs of corals in artificial environments. It's a proven solution for optimal coral growth and coloration, providing you with a stunning and healthy tank. Complete Reef Care replenishes all 36 major, minor, and trace elements that get used up regularly by corals. These elements get used up in relatively predictable ratios, so Red Sea recommends testing calcium once per week to determine the dosages of all 4 parts. How Much Should I Dose?
