Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Spring algea

Ditto what sprkplug said. There are different types of filamentous algae that thrive in different water temperatures. The algae is there because there are enough nutrients and light for it to grow. Once underwater plants start growing and the water temp warms up, it should diminish.

But the suggestion of raking it out is a good one, just make sure to dispose of it away from the pond, so when it decomposes any nutrients can't wash back into the pond.

The dye will help limit light penetration during the winter.
