By nutrients we mean nitrate and phosphate specifically. In the case of phosphates, we can only measure inorganic (dissolved) phosphate. Standard test kits are not very accurate in the low range. I would use Lamotte, Hach, or D & D Merck. SeaChem and Salifert are two of the better hobby-grade (cheaper) kits on the market.
