Potassium complex that promote the Red colors in corals.

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

Coral Colors B 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.

Concentration:
1ml will raise the potassium level of 100 liters (25 gal) by1.75ppm.

All of my corals have great coloration.. I have bleached a couple of acropora and they have bounced back fairly quick and I think I'd have to thank red sea and marine depot for that

REVIEW
I had a large orange cap in a 2 year old 300 gallon tank that was developing gray patches. I added 25 ml per day of this fine product and the patches disappeared in 3 months. I am happy.

Happy Corals!

REVIEW
I run the ZeoVit system on my tank, which tends to deplete Potassium. I've had a hard time finding a potassium supplement that isn't extremely expensive. This stuff works. The dosing chart on the back is handy to avoid doing too much math, and the measuring cup lid is also a great idea.
