The Water-ID Phosphate HR No. 2 reagent tablets are photometer-grade consumables designed to measure high-range phosphate levels (0\u201380 ppm PO\u2084\u00b3\u207b) in pool and spa water using the PoolLab 2.0 photometer. This is the second of two reagents required for the Phosphate HR test \u2014 used alongside the Phosphate HR No. 1 powder pillow (sold separately). Elevated phosphate is a primary nutrient for algae growth, and regular monitoring helps keep pool water clean, clear, and chemically balanced.<\/p>\n
These tablets are exclusively compatible with the Water-ID PoolLab 2.0 photometer. They are not suitable for use with the original PoolLab 1.0 or any other photometer model. Always use photometer-grade tablets \u2014 never rapid-grade tablets, as these lead to incorrect measurement results. Both Phosphate HR No. 1 (powder pillow) and Phosphate HR No. 2 (tablet) must be used together to complete the Phosphate HR test.<\/p>\n
