### Test for Quantifying Dissolved Oxygen in Water
Oxygen (O2) is dissolved in water in the form of gas, which is used by organisms that perform respiration, such as fish, plants, and microorganisms in the biological filter. Reduced concentrations of this gas make fish less resistant to diseases, leading to increased mortality in the tank.
Oxygen is supplied by pumps or compressors in the tank, which pass small air bubbles through the water, known as oxygenators. Temperature, altitude, and salinity inversely affect the concentration of oxygen. Temperature increases of around 5°C lead to a reduction of 0.8 to 1.0 ppm of O2 content.
Each species has specific tolerance limits for the concentration of oxygen in the water; however, tanks with more than 4 ppm (4 mg/L) are considered adequate for the species that are usually raised.
It is important to regularly check the amount of O2 in the tanks, ensuring the well-being of your fish and the proper functioning of the filters.
### Instructions for Use
1. Fill the test tube to the 5 ml mark with the water from the tank to be analyzed.
2. Add 2 drops of reagent solution 1, cap the tube, and gently invert the tube.
3. Add 2 drops of reagent solution 2, cap the tube, and gently invert the tube.
4. Add 2 drops of reagent solution 3, cap the tube, and gently invert the tube.
5. Keep the test tube away from light for 5 minutes, then compare the developed color with the color scale provided in the instructions. Each color shade corresponds to an oxygen (O2) concentration in ml/l or ppm.
