? What is Green Water?
Green water refers to water that has turned green due to a large bloom of phytoplankton. Strictly speaking, green-tinged water with a proliferation of floating diatoms is called green water.

? Effects of Green Water

1. Decomposition of Harmful Substances
As mentioned, green water contains a large bloom of phytoplankton.
In fish keeping, nitrates and phosphates in waste are constant problems. However, by using green water, phytoplankton absorb harmful substances as nutrients and neutralize them.
For general fish keeping, you would purchase a filter to artificially adsorb harmful substances. By using this green water, you can reduce those costs.

2. Food for Medaka
Medaka are omnivorous, but in the wild, they primarily eat plankton.
Examples include zooplankton like daphnia and mosquito larvae, and phytoplankton like diatoms.
Through green water, a food pyramid with medaka at the apex is formed. Phytoplankton bloom → zooplankton eat them → medaka eat the zooplankton → phytoplankton reproduce based on their waste → back to the beginning.
By stabilizing this cycle, medaka are unlikely to starve even without artificial feeding.

【Precautions】
Plants perform both photosynthesis and respiration during the day.
However, on cloudy days or when there is insufficient sunlight, they consume only dissolved oxygen in the water, leading to oxygen depletion for the medaka.
This can rarely occur if the green water is too concentrated, so weak aeration may be necessary. Also, adding aquatic plants or Akadama soil may cause the aquarium water to become clear.
