Hanna Instruments HI-736 Phosphorus Marine Ultra-Low Range Colorimeter - Checker HC
Ideal for use with coral reef tanks and salt water aquariums. While tiny amounts of phosphorus are needed to sustain life in the tank, more phosphorus (as
phosphate) is introduced through feed, decaying plants, animal waste, and even tap water. Too much can deplete oxygen levels, encourage growth of unwanted algae types and inhibit
the calcification by corals and coralline algaes.
Checker range: 0 to 200 ppb.
