Complete Reef Care is a simple but comprehensive 4-part supplement program that ensures optimal coral growth and coloration, that revolves around a single weekly measurement of Calcium, which determines the dosages of all 4 parts.

A successful coral reef aquarium is dependent upon maintaining the appropriate water parameters that provide the stable environment required by the corals. This is achieved by starting with balanced seawater such as using Red Sea or Coral Pro Salt and using complete and balanced supplements, that are formulated to work together for long term use, without changing the ionic balance of the water.

Red Sea’s 4-Part Complete Reef Care is the result of years of research into the physiological demands of SPS, LPS & Soft Corals in the reef aquarium and practical experience with the original 7-Part Reef Care Program on tens of thousands of diverse reef tanks worldwide.

This research has shown that there are 36 Major, Minor and Trace elements that are regularly depleted from the aquarium water and have an active role in coral growth and coloration, as well as other biological activities of the reef environment. In reef systems without refugiums, coral growth is the most dominant biological process that affects the water chemistry, and that the 36 elements, including the Alkalinity components, are used up in a relatively fixed ratio. Since Calcium is the key indicator to coral growth, all the elements can be supplemented according to a measured uptake of calcium.

The Complete Reef Care divides the 36 Major, Minor and Trace elements into four parts to ensure their stability and bioavailability.

• Part #1 contains: Calcium, Magnesium, Strontium & Barium.
• Part #2 contains: KH/Alkalinity components.
• Part #3 contains: Potassium, Boron and the halogens Iodine, Bromine and Fluorine.
• Part #4 contains: Iron, Manganese, Cobalt, Copper, Aluminum, Zinc, Chrome, Nickel plus 18 other bioactive trace elements

Note: If your aquarium utilizes a macro algae refugium, Red Sea recommends using their 7-part Reef Foundation and Trace Colors system instead. This way, you can adjust individual trace elements to account for their unique uptake ratio by macro algae.

ReefDose 4 Ready (sold separately)

The ReefDose 4 conveniently has just the right number of dosing heads for the Complete Reef Care dosing system. When Connected to the ReefDose, your ReefBeat app will automatically adjust the dosages of bottles 2, 3, and 4 based on your selected dosage volume of bottle 1, making automated dosing to your reef tank easier than it's ever been. Better yet, since the four parts are provided in the same ratio that they should be dose in, you'll finish all four bottles at exactly the same time.
