AF Build accelerates the absorption of calcium and carbonate which are crucial for the development of hard corals. By providing the corals with all the necessary ingredients, it facilitates and accelerates calcification, favourably affecting the growth rate. In addition, AF Build raises the pH level in reef aquariums. By keeping the pH at a proper, constant level, it additionally promotes coral growth. Long-term pH level aberrations result with slower calcification, inhibition of limestone algae growth and in extreme cases may completely stop the calcification process.
