Overview

Ponds are a controlled environment, a mini ecosystem. Anything that upsets its natural balance will help algae grow. Some algae is a good thing, because it will clean up debris. But too much algae will go wild and eat things you do not want it to, like the plants that help maintain the oxygen level.

Rain

Too much rain will add nutrients to the pond, upsetting the natural balance and produce food for algae to eat.

Pollen

Pollen stays on the top of the pond making a warm environment for algae to grow. Keep plants that produce a lot of pollen down wind from the pond, if possible. In any case, do not plant them near the pond.

Rotten Foliage

Fallen leaves may give the pond a natural look, but once it starts to decay it becomes food for algae. Rake and pick up any dead foliage around the pond.

Fish Food

Over feeding pond fish will give algae a rich nutrient to eat and grow on. Follow the recommended food dosage for your fish. Over feeding is not good for them either.

Sun

Two much sun combines with the other caused, making them decay at a faster rate. Landscaping with large rock and boulders that will shade the pond during the hottest time of the day will help solve the problem.
