Color Balance is not a product from Tropic Marin. It is from a competing company called Fauna Marin. They are both german companies. It came later after Tropic Marin introduced Reef Actif.
To be honest there is no much information and discussion in german forums about this product. I found one thread where Fauna Marin replied:
"Coral Balance is a very special mixture, the product itself does not act directly but makes bound nutrients and elements available in an aquarium system for the corals and symbiotic bacteria in corals. We use a special mixture of natural marine biopolymers which are partly extracted for us. These are not industrial alginates or simple sugar compounds, as they have the same disadvantages in the long run as all short chain carbon sources. With Coral Balance bound depots are opened and converted into coral biomass, or made skimmable and removed from the system. It is necessary that many different groups of bacteria work together, this results in the important side effect that the bacterial diversity in the system is maintained and the organic components contained in natural seawater also persist in older systems."
