Salifert Dissolved Oxygen Test Kit

• Corals and marine fish require very high levels of oxygen concentration because of the low solubility of oxygen in salt water so it is very important to regularly test the level of oxygen present
• The Salifert Oxygen Profit-Test is extremely fast, measuring oxygen levels in just a few minutes and is scaled from 2 - 14 mg/L
• Sufficient for up 40 tests
• Can be used for marine, fresh and garden pond water
• Made in Holland

Product Description Salifert Oxygen Profit-Test Corals and marine fish require very high levels of oxygen concentration because of the low solubility of oxygen in salt water so it is very important to regularly test the level of oxygen present. The Salifert Oxygen Profit-Test is extremely fast, measuring oxygen levels in just a few minutes and is scaled from 2 - 14 mg/L. Sufficient for 40 tests. Can be used for marine, fresh and garden pond water Warning! Reagent O2-1 is irritating and contains a base. In case of contact with the skin wash with plenty of water. In case of contact with the eyes wash with plenty of water and consult a physician immediately. If swallowed contact a physician immediately. Keep out of reach of children. Not for consumption. Instructions: Add to the test cial 5ml of water. Add 5 drops of O2-1 and swirl gently for 20 seconds. Do not shake since this could change the oxygen content of the water too much. Add 6 drops of O2-2 and swirl gently for 15 seconds. Allow to stand for marine water 5 minutes and other types of water for 1 minute. Add 6 drops of O2-3 and swirl for 20 seconds. Allow 30 seconds for color development. Place the test vial on a white part of the color scheme and compare the colors by looking from above. An immediate color corresponds to an intermediate oxygen content. The values on the color chart are in mg/l (ppm) oxygen. Try to maintain in fresh water (aquarium of garden pond) an oxygen content of 8mg/l or higher. In marine water an oxygen concentration of at least 7mg/l is advisable. Some fish need higher oxygen concentrations. Directions Directions: Add 5ml of water to the cial test. Add 5 drops of O2-1 and gently rotate for 20 seconds. Do not shake as this may affect the oxygen content of the water too much. Add 6 drops of O2-2 and gently rotate for 15 seconds. Let sea water stand for 5 minutes and other water for 1 minute. Add 6 drops of O2-3 and rotate for 20 seconds. Leave 30 seconds for colour development. Place the test vial on a white part of the colour scheme and compare the colours by looking from above. An immediate colour corresponds to an intermediate oxygen content. The values on the colour chart are in mg/l (ppm) oxygen. Try to maintain an oxygen content of 8 mg/l or higher in fresh water (garden pond aquarium). In seawater, an oxygen concentration of at least 7 mg/l is recommended. Some fish need more oxygen concentrations Safety Warning KEEP OUT OF REACH OF CHILDREN. Not for consumption.
