Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Blue dye pros and cons

Hey there Mike and Ted,

I want to give it a shot. It seems to me that your problem might stem from the exchanging water in your pond. There is likely not to be a good phytoplankton bloom on your pond because there are not enough nutrients in the water column, however there are enough nutrients in the soil. When the pond is clear the sun will penetrate to the bottom of the pond and the filamentous algae will get started. Don't get me wrong, there can be fillamentous algae in a fertilized pond, but treatments with diquat can help relieve the problem, also sometimes these problems dicipate as it gets hotter. But if you get the fillamentous alge started at the bottom of the pond, it will be hard to get rid of. Can you divert any of the water that is constantly flowing in to your pond. Runoff is acceptable, but a spring fed pond would constantly be overflowing. Then, if there is as much nutrient runoff as suspected you might be able to develop a plankton bloom before the fillamentous algae get started. If there is not enough nutrients in the runoff FERTILIZE EARLY to try to get a bloom established. Good luck, sorry for all the writing. Aaron
