The Red Sea Phosphate Marine Test Kit provides a quick and reliable method for measuring phosphate (PO4) levels in marine aquariums. Designed for user-friendly operation, this colorimetric test delivers highly accurate results down to 0.1 ppm PO4. When used alongside Red Sea’s Nitrite/Nitrate test kit, it enables precise dosing of NO3: PO4–X, a biological nitrate and phosphate reducer, helping maintain balanced water chemistry for healthy aquarium inhabitants.
