• Measures inorganic phosphate to less than 0.05 mg/L
• Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
• Includes reference for test validation
• Marine or freshwater

Phosphate in natural sea water ranges from less than 0.01 mg/L to 0.3 mg/L. For corals in reef aquaria, such phosphates should be 0.2 mg/L or less. Phosphates are non-toxic to fish and most invertebrates, but are ideally kept below 1 mg/L to minimize algae growth. In freshwater, phosphates are not critical and the allowable concentration is dependent on variables such as nitrate, manganese, iron, and vitamin concentrations, as well as the extent of use of live plants.

MultiTest™ Phosphate measures inorganic phosphate to less than 0.05 mg/L, producing a unique easy to read yellow-green-blue color range in marine and freshwater; however, usually, freshwater phosphate concentrations will be beyond the range of this kit, and dilutions of the sample with distilled water will be required. It performs over 75 tests and contains a reference sample for validation.

Accuracy

Range

Measures between 0–3.0 mg/L phosphate

Precision

Detectable changes on the color chart in 0.001–0.1 mg/L increments

Color Chart

All MultiTest™ test kits come with an easy-to-read color chart. It features a 5 cm viewing window to help isolate color and match as closely as possible to the test sample

Opaque Multi-Cavity Test Plate

All MultiTest™ test kits are read from an opaque white test plate. The sliding color chart along with the six-cavity test plate allows for easy reading and comparisons of several samples at the same time.
