Whether you have too much or too little, many different problems can stem from inappropriate levels of oxygen in your pond or lake. If you want a healthy pond you will have to learn to manage it. There are a few ways to go about this.
When looking at oxygen in water, it is referred to as dissolved oxygen (DO). It is usually measured in parts per million (ppm). There are three main methods of determining dissolved oxygen concentrations in water:
- An electrochemical or optical sensor, which is the most accurate
- Colorimetric sampling, which will give you a basic approximation
- Winkler titration, which is accurate, but more difficult than other methods
If your dissolved oxygen levels are decreased below 6 ppm, you will probably notice some sort of algal bloom happening in your pond. Usually an increase in your levels of nitrogen and phosphate is what causes …Read More
