Exactly which aquarium additives to use is a complicated question. However, all reef aquariums will need either calcium or kalkwasser (or both), supplements and buffer.
  • Buffer is used to maintain pH. We recommend the Inland Seas Marine and Reef Buffer.
  • You can use several types of supplements or just use a comprehensive formula such as the Inland Seas Biotrace, which includes Strontium, Iron, Iodine, Molybdenum, Vitamin C and B12, as well as other trace elements, vitamins, and amino acids.
  • It is necessary to add calcium/kalkwasser to reef aquariums in order to replenish the calcium utilized in the growth of soft and stony corals, pink coralline algae, calcareous algae, tridacna clams, and other invertebrates found in captive marine systems.
To raise certain types of corals you may want to add extra Iodine, Strontium, Maganese and Molybendum. Kent Marine offers an extensive line of aquarium additives specifically for Iron, Strontium, etc.

The Brightwell Aquatics line of products is a line of aquarium water treatment additives created by the scientist who developed the original Kent Marine line of aquarium additives.

The Red Sea Reef Foundation, Coral Colors and Reef Energy supplements are all part of the integrated Red Sea Reef Care Program. We have many links to documentation and videos that explain how to use these additives, along with the Red Sea Pro Test Kits to create a healthy and vibrant reef aquarium.

Other additives are useful aquarium water treatments, such as Kordon AmQuel, which effectively removes ammonia, chloramines, toxic pheromones and chlorine in both freshwater and saltwater aquariums.
