Description
High-Precision Colorimetric Phosphate Test
The Red Sea Phosphate Pro Test Kit is an advanced colorimetric test designed to measure phosphate (PO₄³⁻) levels in reef aquariums with exceptional accuracy of ±0.02 ppm. Maintaining precise phosphate levels is crucial for preventing algae growth and ensuring healthy, vibrant coral.
When used alongside the Nitrate Pro Test Kit, it enables precise dosing of Red Sea NO3:PO4-X, a biological Nitrate & Phosphate reducer, as part of the complete Red Sea Reef Care Program.
