Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of Nitrates in a reef aquarium can promote the growth of undesirable organisms including algae and dinoflagellates, while insufficient amounts can lead to starvation in which SPS, and other corals, will show signs including the loss of colour and paleness.
