Salifert Oxygen Profi-Test Kit for Aquarium 50 Tests

The Salifert profi-test is a professional-grade aquarium test kit designed to quickly measure dissolved oxygen levels ranging from 2 to 14 mg/L (ppm). It delivers accurate results within minutes and is suitable for marine, freshwater, and garden pond water. This kit contains enough reagents for about 50 tests, making it a cost-effective solution for monitoring aquatic environments. Maintaining proper oxygen levels is crucial for the health of corals and marine fish, which require high oxygen concentrations due to oxygen's low solubility in saltwater. It pairs well with marine supplements to keep aquatic life thriving in optimal conditions.

• The kit contains three main reagents: O2-1, O2-2, and O2-3.
• O2-1 reagent is a base-containing solution that initiates the oxygen reaction.
• O2-2 and O2-3 reagents develop a color proportional to oxygen concentration.
• Reagents are designed for use with 5 ml water samples.
• Handling requires care as reagents include irritants; follow safety guidelines.

• Store the test kit and reagents in a cool, dry place away from direct sunlight and temperature extremes.
• Keep all reagents and equipment out of reach of children to prevent accidental ingestion or contact.
• Wear safety glasses and avoid contact between reagent chemicals and skin, eyes, or mouth.
• Always read reagent labels and instructions before starting; note first aid information for accidental exposure.
• Tightly close all reagent containers after use and do not interchange caps to avoid contamination

• Add 5 ml of water to the test vial.
• Add 5 drops of O2-1 reagent and gently swirl for 20 seconds without shaking.
• Add 5 drops of O2-2 reagent, swirl for 15 seconds, then let it rest for 3 minutes (marine water) or 1 minute (freshwater).
• Add 5 drops of O2-3 reagent, swirling for 5 seconds after each drop, then wait 1 minute for color to develop.
• Place the vial against the white color chart and compare colors from above to determine oxygen concentration.
