Phosphate PO4 Profi Test Salifert

Profi test Phosphate allows you to control the phosphates present in your saltwater aquarium. This product, in two solutions, allows you to perform 60 tests. Our opinion: Salifert tests are reliable and very affordable.

Warning! Keep out of reach of children. PO4-1: Causes severe eye irritation. Wear protective gloves / eye protection equipment. IN CASE OF CONTACT WITH EYES: rinse cautiously with water for several minutes. Remove contact lenses if the victim is wearing them and they can be easily removed. Continue rinsing. If eye irritation persists: consult a doctor. Incorrect results may be obtained when the carbonate hardness is above 20 dKH. Normally, the carbonate hardness is much lower than this value.

INSTRUCTIONS:

1] Pour 10 ml of water into the test tube using the syringe.

2] Add 4 drops of PO4-1 reagent and gently swirl the test tube for 10 seconds.

3] Add 1 spoonful of PO4-2 powdered reagent and gently swirl the test tube for 30 seconds.

4] Place the open test tube above the colorimetric scale, in a place where there is white, and compare the colors. Deduce the phosphate concentration. The indicated values are in ppm of phosphate. If you prefer a reading in ppm of phosphate-phosphorus, then divide the obtained value by 3.

INCREASE SENSITIVITY: If you need higher sensitivity, double the volume of the water sample and the reagents. The obtained value should then be divided by 2.
