Full Details

Red Sea Reef Energy Dosing Recommendations*:

  • Soft Corals Tank - 1 mL/25 gallons
  • LPS Tank - 2 mL/25 gallons
  • SPS - accelerated growth/mature tank - 2 mL/25 gallons
  • SPS - enhanced colors (low nutrient) tank - 4 mL/25 gallons


Calculate the total water volume of your system (aquarium and sump minus live rocks, etc.). Mix Reef Energy A and B together directly for dosing.


*These doses are recommended starting points based on a well-stocked tank. Adjustments may need to be made. Be sure to monitor the appearance of your corals for signs of overdosing - fluctuations in nitrate and phosphate levels as wells as the development of bio-film on rocks or an algae breakout are signs that dosing changes may be necessary. Follow manufacturer's instructions.


Refrigerate after opening.

  • Great product. By Millz on 1/30/2017

    I absolutely love RED Sea products. They're putting their money where their mouth is. This is a much needed item in the reefing community.
  • A Must Have By Matt on 1/10/2017

    I have used many products that claim a lot of things with little results. I use Reef Energy A and B along with Reef Colors A,B,C & D. I have seen the best growth, color and overall better health for my aquarium since using. I would highly recommend!
  • good product By Zack on 12/8/2016

    I have seen improved colors and extension, I see no reason not to use it.
  • A must for anemones By John on 11/21/2016

    Immediate coloration in flower anemones. Zoas multiply faster. Just give it some time on the acros.
  • Great product By Robsyp on 6/22/2016

    Great product can see a improvement in growth since the start of using it.
  • Noticeable Growth By Chavinpat on 6/11/2015

    Read and follow instruction carefully. Noticeable Growth
  • So far so good By Anthony on 1/29/2015

    So, I have been using this since I set my tank up and added coral. Its easy to use, read bottle do math dump in tank. I am using A&B together. I have noticeable growth in my corals. The coloration is good in my SPS and I surprise some of the guys in the area that have been at this for much longer than me. After we move I plan on setting two systems side by side and documenting the growth using A&B in one tank and not in the other. If I notice a difference or not I will redo my review at that time.
  • Good product By tony on 1/25/2015

    I have been using A & B for about two months and have seen better colors and extension. I would recommend this product
  • Success! By dextereef on 1/23/2015

    I have tried several other products out there and I have only seen a response from my corals while using A&B. Good stuff.
  • Great Product By rsteinberg on 1/8/2015

    I use both A and B with great results It is easy to use and i have seen Huge growth and way brighter colors.
  • Bad batch By nanodoc on 9/1/2014

    I have used the smaller bottles of Reef Energy A & B with good results , so I decided to buy the 500 ml bottles.
    However, I found algae or an algae like substance in the A bottle.
    I wonder if others have experienced the same because the bottle was sealed, meaning it might have been a bad batch.
    I still would use it again.
  • Impressive!! By Starboard on 4/24/2014

    I've used other products in the past with little notice to its affects on my mixed reef . After using Red Sea A&B product I have seen double growth rate and overall healthy looking colonies and the polyp extension on my sps , WOW! The only thing that disappoints me is that they don't offer 128 oz. since I have a 200+ gallon system this stuff doesn't last me a month so I have to dose every other day to every three days to make it cost effective for me. Even by under dosing from the standard I see great results. Just buy it and you'll see!
