Seachem MultiTest Phosphate

Phosphate in natural seawater ranges from less than 0.01 mg/Ltr to 0.3 mg/Ltr. For corals in reef aquaria, such phosphates should be 0.2 mg/Ltr or less. Phosphates are non-toxic to fish and most invertebrates, but are ideally kept below 1 mg/Ltr 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.

Seachem MultiTest Phosphate measures inorganic phosphate to less than 0.05 mg/Ltr, 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.

 

Color Chart

The Seachem MultiTest Ammonia test kit comes 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

The Seachem MultiTest test kit is 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.
