Corals and marine fish require very high amounts of oxygen due to the low solubility of oxygen in saltwater. It is very important to regularly check the oxygen content.

The Salifert oxygen test provides very fast results, as it shows the oxygen content in a few minutes in areas of 2 meters 14 mg / l.

Instructions:

• Add 5 ml of water to the test vial.
• Add 5 drops of O2-1 and shake gently for 20 seconds.
• Add 6 drops of O2-2 and shake gently for 15 seconds.
• Add 6 drops of O2-3 and shake for 20 seconds.
• Place the test vial on a white part of the color combination and compare the colors by looking from above.
