Absolue Red is a highly concentrated potassium solution which helps to improve the colouration and growth of SPS corals. Maintaining potassium within the range of 390 – 410 ppm is important as it is a major element in seawater. Absolue Red is a well-balanced supplement that effectively raises and maintains the correct potassium levels in reef systems.

Potassium is essential for the formation of red and pink coral pigments in montiporas, pocilloporas, birdnest, styloporas, seriatoporas and acropora.
