Nutrafin’s Phosphate (0.0 - 1.0 mg/L) Test measures phosphate in fresh and saltwater aquariums. Phosphate levels should be monitored weekly. High levels of phosphate, often the result of overfeeding or infrequent water changes, can contribute to unsightly algae growth. Therefore, phosphate should generally never exceed 1 mg/L.

The kit provides up to 75 tests and includes :

•  One 10 mL (0.3 oz) bottle of Phosphate reagent #1
•  One 10 mL (0.3 oz) bottle of Phosphate reagent #2
•  One 10 mL (0.3 oz) bottle of Phosphate reagent #3
•  One glass test tube with cap
•  One pipette
•  One lab base
•  One instruction booklet
