1. Protein build-up: As fish swim and breathe, they release proteins and other organic matter into the water. These proteins can form bubbles when they come into contact with air or when the water is agitated.
2. Decomposing organic matter: When plants or animals die and decompose in the water, they release gases that can form bubbles.
3. Soap or detergent: Even small amounts of soap or detergent can cause bubbles in the water. This can happen if you accidentally spill soap into the pond or if rainwater runoff carries soap from your yard into the pond.
4. High pH levels: High pH levels can cause the water in your fishpond to become more alkaline, which can lead to the formation of bubbles.
5. Air bubbles from filters: If your fishpond has a filter that uses air to create a current, it can also produce bubbles.
In most cases, white bubbles in a fishpond are not harmful to fish. However, if the bubbles are excessive or if they are accompanied by other water quality problems, it's important to take steps to identify and address the cause.
Here are some tips for reducing white bubbles in your fishpond:
* Regularly skim the water surface to remove protein build-up and other debris.
* Remove dead plants and animals from the pond as soon as possible.
* Avoid using soap or detergent near the pond.
* Test the water pH levels regularly and adjust as needed.
* If you have a filter that uses air, make sure it's not producing excessive bubbles.
