When most reef keepers think about coral health, they immediately focus on lighting, water flow, calcium, alkalinity, and magnesium. While these factors are undoubtedly important, many beginners overlook another essential aspect of reef keeping: coral nutrition.
Just like fish require food to thrive, corals also need a consistent source of nutrients to support growth, colouration, tissue development, and overall health. Although corals obtain energy from the symbiotic algae living within their tissues, they also actively consume nutrients from the water column.
This is where Red Sea Reef Energy Plus A & B comes in.
Developed as part of Red Sea's comprehensive Reef Care Program, Reef Energy Plus provides a complete nutritional solution designed to maximise coral growth, improve colouration, and enhance vitality in both mixed reefs and SPS-dominated aquariums.
In this beginner's guide, we'll explain what Reef Energy A & B is, how it works, why corals need supplemental nutrition, and how to use it effectively in your reef aquarium.
Why Do Corals Need Feeding?
Many new reef keepers assume that corals survive entirely through photosynthesis.
While it's true that corals receive a significant amount of energy from their symbiotic zooxanthellae algae, this only tells part of the story.
In the wild, corals also consume:
- Dissolved organic compounds
- Amino acids
- Fatty acids
- Carbohydrates
- Plankton
- Suspended particles
This additional nutrition supports:
- Tissue growth
- Colour development
- Skeletal formation
- Reproduction
- Recovery from stress
In closed aquarium systems, these nutrients are often limited.
Supplemental feeding helps bridge that gap.
What Is Red Sea Reef Energy Plus?
Red Sea Reef Energy Plus is a complete coral nutrition supplement designed to provide all major energy components required by corals.
The latest Reef Energy Plus formula combines the benefits of the original Reef Energy A and Reef Energy B products into a single easy-to-use solution.
It contains:
- Carbohydrates
- Amino acids
- Fatty acids
- Vitamins
- Trace organic compounds
All supplied in a form that corals can readily absorb.
Why Was Reef Energy Developed?
Red Sea developed Reef Energy after extensive research into coral nutritional requirements.
The goal was to provide:
- Improved coral growth
- Enhanced colouration
- Increased polyp extension
- Better skeletal development
without significantly increasing nutrient levels in the aquarium.
The result is a highly concentrated supplement designed specifically for reef aquariums.
Which Corals Benefit from Reef Energy?
One of the strengths of Reef Energy is its broad compatibility.
SPS Corals
Examples include:
- Acropora
- Montipora
- Stylophora
- Pocillopora
LPS Corals
Examples include:
- Euphyllia
- Acanthastrea
- Favia
- Lobophyllia
Soft Corals
Examples include:
- Zoanthids
- Mushrooms
- Leather corals
Virtually all photosynthetic corals can benefit from improved nutrition.
Understanding How Corals Feed
Corals utilise multiple feeding methods simultaneously.
Photosynthesis
Zooxanthellae algae produce energy from light.
Direct Absorption
Corals absorb dissolved nutrients directly from the surrounding water.
Particle Capture
Many species actively capture suspended food particles.
Reef Energy supports these natural feeding mechanisms by providing highly available nutrients.
Benefits of Reef Energy Plus
When used correctly, hobbyists often report significant improvements in coral health.
Enhanced Coral Growth
Well-fed corals generally grow more quickly.
Improved Colouration
Healthy tissue often results in stronger pigmentation.
Increased Polyp Extension
Many corals display improved feeding responses.
Better Tissue Development
Corals often appear fuller and healthier.
Increased Resilience
Proper nutrition can help corals recover more effectively from stress.
These benefits are often most noticeable in SPS-dominated systems.
How Reef Energy Differs from Coral Foods
Many reef keepers confuse Reef Energy with traditional coral foods.
There are important differences.
Traditional Coral Foods
Typically contain:
- Particulate foods
- Phytoplankton
- Zooplankton
These foods often rely on active feeding responses.
Reef Energy Plus
Provides:
- Dissolved nutrients
- Amino acids
- Organic compounds
which can be absorbed directly by coral tissues.
This makes Reef Energy suitable for a wider range of coral species.
Does Reef Energy Replace Coral Foods?
Not necessarily.
Many reef keepers combine Reef Energy with other feeding methods.
For example:
Reef Energy Plus
Provides daily nutritional support.
Target Feeding
Provides additional nutrition for specific corals.
Broadcast Feeding
Offers suspended particulate foods.
Together, these approaches can create a comprehensive feeding strategy.
How to Dose Reef Energy Plus
One of the biggest advantages of Reef Energy is its simplicity.
General Dosing Method
Dose directly into a high-flow area of the aquarium or sump.
This allows nutrients to circulate throughout the system.
Daily Dosing
Red Sea recommends daily feeding for optimal results.
Smaller, consistent doses generally produce better results than large occasional feedings.
Should Equipment Be Turned Off?
Unlike many coral foods, Reef Energy does not necessarily require shutting down filtration systems.
However, some hobbyists choose to:
- Reduce skimmer activity temporarily
- Pause filter rollers briefly
to maximise nutrient availability.
Follow Red Sea's recommendations and observe your aquarium's response.
How Long Before You See Results?
Coral nutrition is a long-term strategy rather than an instant solution.
Typical Timeline
Within Days
- Increased polyp extension
Within Weeks
- Improved tissue fullness
- Better colour intensity
Within Months
- Increased growth rates
- Enhanced skeletal development
Consistency is important.
Monitoring Nutrient Levels
While Reef Energy is designed to be highly efficient, it still adds nutrients to the system.
Regular testing remains essential.
Monitor
- Nitrate
- Phosphate
Balanced nutrient levels help maximise coral health while minimising algae issues.
Common Beginner Concerns
Will Reef Energy Cause Algae?
When dosed correctly and combined with proper nutrient management, algae problems are unlikely.
Overdosing, however, can contribute to elevated nutrient levels.
Can It Be Used in New Aquariums?
Yes, although coral demand is often lower in newly established systems.
Is It Safe for Fish and Invertebrates?
Absolutely.
Reef Energy is reef-safe and suitable for mixed reef aquariums.
Combining Reef Energy with the Red Sea Reef Care Program
Reef Energy works particularly well alongside other Red Sea products.
Reef Foundation
Maintains:
- Calcium
- Alkalinity
- Magnesium
Trace Colours
Supports coral pigmentation.
NO3
Helps manage nutrients.
Together, these products form a complete reef care strategy.
Signs Your Corals May Benefit from Additional Nutrition
Common indicators include:
Reduced Growth
Corals appear stagnant.
Pale Colouration
Pigmentation becomes less vibrant.
Poor Polyp Extension
Feeding response is limited.
Thin Tissue
Corals appear less full than normal.
While multiple factors can contribute to these issues, nutrition is often part of the equation.
Common Feeding Mistakes
Overdosing
More is not always better.
Ignoring Nutrient Testing
Always monitor nitrate and phosphate.
Inconsistent Feeding
Daily routines often produce the best results.
Expecting Instant Results
Coral health improvements take time.
Patience is essential.
Is Reef Energy Worth It?
For many reef keepers, Reef Energy becomes one of the most noticeable additions to their maintenance routine.
Particularly Beneficial For
- SPS-dominated reefs
- Mixed reef aquariums
- Coral growers
- Frag systems
When combined with stable water chemistry and appropriate lighting, Reef Energy can significantly enhance coral performance.
Frequently Asked Questions
Do Soft Corals Need Reef Energy?
While their demands are generally lower, many soft corals still benefit from supplemental nutrition.
Can Reef Energy Be Used with Automatic Dosing Systems?
Yes.
Many hobbyists automate daily dosing for greater consistency.
Should I Feed Every Day?
Daily dosing is generally recommended for optimal results.
Can I Overfeed Corals?
Yes.
Excessive dosing may contribute to nutrient accumulation.
Always follow recommended guidelines.
