The Delicate Balance of Walkers Pond
…. Not just our pond, every pond. I recently learned that alga is a weed that is airborne. They release spores that travel in the air spreading algae from pond to pond.
Algae compete with fish for water borne nutrients while other nutrients are borne on algae for fish to ingest. Results, you could create a sterile pond if the appropriate use of use of herbicides and algaecides isn’t applied correctly.
The Filamentous algae growing around the edge of our pond provide shelter for small fish. These minnows eat mosquito larvae then they provide bigger fish with a food source. The food chain. A little alga around the pond is a good thing, but you can’t allow it to grow uncontrolled. That’s why treatment with herbicides and algaecides is necessary.
The Spartina grass that we planted has the ability to contain runoff of nutrients from yard fertilizers. We don’t need fertilizer in the pond. If you must use a weed and feed, please don’t use it by the pond.
The water chemistry is so important to the health and beauty of our pond. If you want to continue seeing those shorebirds we can’t have a sterile pond.
