Will algae in a pond go away on its own?
Plants, plants and more plants. The green free floating algae will eventually starve. The reason you are not getting any readings on your water tests is because the algae is consuming the nutrients.
How long does it take for pond algaecide to work?

Should I leave algae in pond?
The Good: Algae is not harmful to your pond or water feature.

What kills algae in a pond?
Treat the pond water with algaecides. If you can’t clean your water and remove your algae any other way, you can use algaecides to treat the water and kill the algae. Purchase an algaecide or herbicide that contains copper and spray it over your pond to begin killing off the algae.
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. Be careful with carp, koi and other bottom feeders. While they eat algae, they can also make your pond look dirty.
How do I reduce algae in my pond naturally?
This is perhaps the simplest, long-term solution to keeping water clean and clear. Floating plants, such as lilies and lotus, provide shade and reduce direct sunlight in the pond to control the growth of algae. Add submerged plants that release oxygen to the water, such as anacharis, hornwort and parrot’s feather.
What happens if there is too much algae in a pond?
Algae is beneficial to an aquatic ecosystem; however, when levels get too high there can be problems. Some algae can release toxic compounds, but the most common source of fish kills related to algae is oxygen depletion. It is the extraction of oxygen for respiration in water at night that causes most fish kills.
When should you treat algae in a pond?
