The Red Sea 4 Part Complete Reef Care Program is a coral supplementation system designed specifically for non-refugium reef aquariums. Red Sea developed the program from years of research and practical experience with thousands of reef tanks, and it delivers balanced supplementation of all 36 major, minor, and trace elements corals need for growth and coloration.
Why Choose the Red Sea Reef Care Program?
- Simplified routine: just four bottles, with a single weekly calcium test determining the dose for each part
- Complete elemental support: replenishes the elements corals deplete to keep water chemistry balanced
- Fixed ratio dosing: every element is adjusted based on calcium uptake
- Less waste: elements are supplied in the proportions corals use them, so all four parts run out at the same time
- ReefDose compatible: set the initial dosage and ReefDose automatically recalibrates the doses of the other parts as calcium levels change
What's in Each Part?
| Part | Elements |
|---|---|
| Part 1 | Calcium, magnesium, strontium, barium |
| Part 2 | KH/alkalinity components |
| Part 3 | Potassium, boron, and halogens (iodine, bromine, fluorine) |
| Part 4 | Iron, manganese, cobalt, copper, aluminum, zinc, chrome, nickel, and 18 other bioactive trace elements |
How Fixed Ratio Dosing Works
Red Sea's long-term studies found that in reef systems without a refugium, essential elements are consumed in a consistent ratio. The program uses that ratio so calcium uptake can guide the dosing of every other element. Test calcium once a week, and that single result sets the dose for all four parts. Because the elements are consumed together, you finish every bottle at the same time rather than running out of one part early.
Choosing a Pack Size
| Pack | Suitable For | Approximate Duration |
|---|---|---|
| Small | 40-gallon mixed reef | About 3 months |
| Medium | 80-gallon mixed reef | About 3 months |
| Large | 160-gallon mixed reef | Up to 3 months |
Getting Started
Begin with Red Sea or Coral Pro Salt for balanced seawater, then use the Red Sea Complete Reef Care Program to maintain long-term stability without altering the ionic balance of your aquarium water. If you are transitioning from a 7-part program, the 4-part system consolidates your routine into fewer bottles and one weekly test. The program is equally suited to starting a new reef.
Note that the fixed dosing ratio is based on non-refugium systems, so it is the best match for reefs without a refugium.
