You can still see green water about 3 weeks after adding fish. About 5-6 weeks after it will have naturally turned to blue. If you are not sure if your fish is getting enough oxygen, you can test it by putting a small amount of water in the tank. If the water turns blue, it is probably getting too much oxygen.

There’s even a video explaining it all!

How do I get rid of algae in my pond without killing the fish?

Place a bundle of barley straw on a large upside-down plastic pot in the pond, so that the bundle is just submerged underneath the water. Around 1,000 gallons of pond water is treated with an 8-ounce bundle of treats. When exposed to sunlight and oxygen, the straw will break down.

The answer depends on the type of algae you are dealing with. For example, some types of algaes, such as blue-green algae, can take up to a year to completely disappear from a pond. Other types, like white-spotted algal blooms, will disappear in as little as two weeks.

Why is my pond turning green so quickly?

Green water is most commonly caused by excess nutrients in the pond (high nitrates from decomposing waste) – or high phosphates from fertilizer runoff or excess fish food. Plants, plants, and more plants are the best treatments. Nitrate levels are measured in parts per million (ppm). If your pond has a high number of ppm, you may need to add more fertilizer or water changes to correct the problem.

Does green pond water harm fish?

Although green water can be treated with algicide and Flocculating Chemicals, these are short term solutions and can have side effects if used without accompanying filters. If green algae die back all at once, they can pollute the water supply. This can lead to algae blooms in lakes, rivers, and streams, which can kill fish and other aquatic life.

Why is my pond full of algae?

Issues with floating algae growth can be caused by factors like too much sunlight and excess nutrients. Overfeeding fish, stocking too many fish, and a lack of proper filtration are some of the causes of excess nitrogen in the pond.

If you see algae growing on the bottom of your pond, you may need to reduce the amount of fish you are stocking in order to keep the algae at bay. If you have a pond with a lot of algae, it may be a good idea to remove some of the fish from the water.

How do I keep my pond algae free?

Sunlight is important for the growth of algae. We recommend shading 40% of your pond’s surface area by covering your water with pond water lilies or other floating plants. Adding plants helps prevent the blooms of algae in the pond.

What eats algae in a pond?

Fish that clean ponds by eating algae and other debris include the common pleco, the mosquitofish, the Siamese algae eater and the grass carp. You should be careful with the bottom feeders. They can make your pond more acidic by eating algae.

If you have a pond with a lot of fish, it’s a good idea to keep them in a separate tank from the rest of the fish. This way, you won’t have to worry about them eating each other, and you’ll be able to monitor their health.
