Profi Test Oxygen Salifert – O2 Test for Marine Aquarium

The Oxygen Test Salifert Profi Test allows for precise measurement of the dissolved oxygen concentration in seawater. The oxygen level is a crucial parameter for the respiration of fish, invertebrates, and the proper functioning of biological bacteria.

This test is designed for a measurement range between 2 and 14 mg/L and allows for approximately 40 measurements. Salifert tests are recognized for their reliability, precision, and accessibility in marine aquariums.

Main Features

• Test type: dissolved oxygen (O2)
• Measurement range: 2 to 14 mg/L
• Use: marine aquarium and seawater
• Number of tests: approximately 40
• Reading by colorimetric comparison

Safety Information

Warning. Keep out of reach of children.

The O2-1 reagent causes skin irritation and severe eye irritation. Wear protective gloves and eye protection equipment.

In case of skin contact, wash thoroughly with water and soap. If skin irritation persists, consult a doctor.

In case of eye contact, rinse cautiously with water for several minutes. Remove contact lenses if possible and continue rinsing. If irritation persists, consult a doctor.

Contains NaOH < 2% (sodium hydroxide).

Instructions for Use

1. Pour 5 ml of water to be tested into the test tube.

2. Add 5 drops of the O2-1 reagent and gently stir for 20 seconds. Do not shake vigorously to avoid altering the oxygen content of the water.

3. Add 5 drops of the O2-2 reagent and gently stir for 15 seconds. Let it sit for 3 minutes for seawater or 1 minute for other types of water.

4. Add 5 drops of the O2-3 reagent, stirring for 5 seconds after each drop. Then wait 60 seconds for the color to develop.

5. Place the test tube above the colorimetric scale, on a white surface, and compare the resulting color. An intermediate color corresponds to an intermediate concentration.

The values are expressed in mg/L (ppm) of dissolved oxygen.

Recommended Values

It is advisable to maintain a concentration of at least 6 mg/L of oxygen in a marine aquarium. In freshwater, a value of 8 mg/L or more is recommended.

Some fish and invertebrates may require higher oxygen concentrations.

Regular monitoring of dissolved oxygen helps optimize circulation, aeration, and the overall health of the aquarium.
