I love the fact that Elos also makes Omega Amino Acids and zooplankton! I think people really underestimate coral's need for plankton and the aminos that plankton provides. I dig the idea of not refrigerating my zooplankton, and that it is kept in a contaminate free bag for protection.
Since I am in need of a new Nitrate test kit. I really like the ease of use and the scale of color. This one seems very easy to read and differentiate between the readings.
