• Trace Colors B - Potassium


Potassium and Boron supplement that promotes the Red colors in corals

K | B

POTASSIUM+ Supplement is part of the complete range of complementary major, minor and trace element complexes which together provide the needs of corals.

POTASSIUM+  Supplement contains potassium and boron that are associated with many biological processes, one of them being the production of the red pigments in the soft tissue of corals.

Potassium plays an essential role in the transportation of coral nutrients within the soft tissue (including the nutrients provided by the zooxanthellae). Potassium and boron significantly affect the alkalinity of a coral’s soft tissue and the formation of aragonite in its skeleton. Potassium is related to the red chromo-proteins.

For best results in displaying coral colors use Red Sea’s NO3: PO4– X.


Provides the 31 minor and trace elements necessary for coral vitality and color



Red Sea Coral Coloration Program – Spice up your colors.

Red Sea’s research has identified 31 minor and trace elements that in addition to the foundation elements are present in the skeleton and soft tissue of all corals.

The Red Sea Coral Coloration Program’s supplements family divides these elements into four groups : Trace – Colors A, B, C and D that are related by the biological functions they perform. They are also associated with the production of specific color pigments in the soft tissue of stony corals.

These pigments can only be produced if the specific elements required for the bio-chemical process are available in the correct concentration. All 31 elements are required by all stony corals irrespective of the actual color the coral displays.

Easy supplementing according to Calcium

Red Seas’ Coral Color supplements have been formulated such that the ratio of the elements in each supplement is the same as that found in the skeleton and soft tissue of corals.

Our research has identified a constant ratio between each of the elements in our Trace-Colors supplements and the overall consumption of calcium, which is proportional to coral growth and metabolic activity. This provides an easy and safe method of dosing all Trace Colors Supplements based on a measured calcium uptake.

Coral Colors A, B and C each contain a leading element (iodine, potassium and iron) that is accurately measurable with Red Sea’s unique Trace-Colors Pro Test Kits. For ultra low nutrient systems Trace Colors A, B and C should be dosed precisely according to the measured demand of the reef for these elements.
