The benefits and information of Red Sea Complete Reef Care Large
Optimal Growth and Coloring
Red Sea Complete Reef Care guarantees rapid coral growth and vibrant coloring. Backed by extensive research, this 4-part program divides the 36 essential elements into precise components, ensuring that each necessary element is available in ideal proportion. Corals benefit from maximum bioavailability, allowing them to develop strong skeletons and vibrant colors, while minimizing the risk of chemical imbalance.
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, Chromium, Nickel and 18 other bioactive trace elements.
Simplified Settings Management
With just one weekly Calcium test, Complete Reef Care greatly simplifies managing your aquarium parameters. Doses of all four parts are automatically adjusted based on Calcium test results, eliminating the need for multiple tests and adjustments. This allows aquarists to focus more on observing and enjoying their reef, rather than tedious maintenance.
Compatibility with ReefDose
Compatibility with Red Sea ReefDose makes supplement administration even easier. Once the Calcium dose is programmed, the ReefDose automatically adjusts the dosages of the other three components. This ensures precise and consistent distribution of essential elements, reducing human error and maintaining the perfect balance in the aquarium.

Long Term Stability
Complete Reef Care ensures long-term stability of water parameters, crucial for coral health. Major, minor and trace elements are consumed in a fixed ratio, ensuring that no element becomes limiting. This chemical stability helps maintain optimal conditions for corals, promoting their continued growth and development, while preventing harmful fluctuations.
