  • 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.

  • Ideal for aquariums and marine biology
  • Easier to use and more accurate than chemical test kits
