Monitor nitrate and phosphate levels in conditioned aquariums and replacement (source) water for optimum water quality. Though not significantly toxic, nitrate and phosphate can potentially be harmful in higher concentrations. These compounds are nutrients and often encourage the growth of nuisance algae. Easy-to-use and accurate individual test kits simplify the testing of these chemicals. Ideal for use with all marine, reef, and freshwater aquariums. Features fast-dissolving, foil-packed granular test chemicals, and transparent color chip right next to the test chamber for easy reference. Color chips are calibrated to ensure reliable test results. 20 tests each per Kit/Refill.

• Nitrate Test - Range: 0 to 100 milligrams/liter Nitrate-Nitrogen (NO-3-N)
• Phosphate Test - Dual Range (high and low level readings): 0 to 1.0 and 0 to 5.0 milligrams/liter Phosphate (PO43-)
