PO4-Test Freshwater / Seawater TROPIC MARIN

PO4 Test Tropic Marin for Freshwater and Marine Aquariums

The PO4 Test Tropic Marin allows measurement of phosphate concentration in both freshwater and marine aquariums. Phosphate is an essential nutrient for cellular metabolism, but excessive accumulation can cause biological imbalances and promote algae proliferation.

About Phosphate

Phosphates are essential nutrients for all plants and for the energy metabolism of every living cell. They enter aquarium water through distributed food and natural decomposition processes.

Uncontrolled increases in phosphate concentration promote excessive algae growth. In marine aquariums, it can also complicate the precipitation of calcium carbonate needed for forming the calcareous skeleton of hard corals, thus compromising their growth.

Conversely, in aquariums heavily populated with plants or corals and lightly populated with fish, phosphate can become limiting and require rebalancing.

In freshwater aquariums, a concentration up to 0.4 mg/L is generally acceptable, without exceeding 1 mg/L. A value of 0.02 mg/L is already sufficient for the nutritional needs of aquatic plants. In natural seawater, phosphate concentration is around 0.06 mg/L. In marine aquariums, it is recommended not to exceed 0.15 mg/L and to maintain coral aquariums between 0.03 and 0.1 mg/L.

Usage and Measurement Principle

The measurement is carried out by colorimetric comparison. A reference cuvette is used to facilitate precise reading of the final coloration. After the development time, the obtained color is compared to the provided color chart to determine the phosphate concentration.

The reading should be performed under light close to daylight to ensure a reliable match between the sample and the reference colored area.

Durability and Storage

The reagents are usable for up to 6 months after opening. They should be stored in a dark and cool place to ensure the reliability of the results.
