What is Green Water?

Green Water refers to water that has turned green due to a large bloom of phytoplankton. Strictly speaking, it is greenish water where plankton, primarily floating diatoms, have proliferated.

Effects of Green Water:

1. Decomposition of Harmful Substances

As mentioned, Green Water contains a large bloom of phytoplankton.

Nitrates and phosphates from fish waste are a constant problem in fish keeping. However, by using Green Water, phytoplankton absorb these harmful substances as nutrients, effectively neutralizing them.

For general fish keeping, filters are purchased to artificially adsorb harmful substances. Using Green Water can reduce these costs.

2. Food Source for Medaka

Medaka are omnivorous, but in the wild, they primarily feed on plankton.

This includes zooplankton like daphnia and mosquito larvae, and phytoplankton such as diatoms.

Through Green Water, a food pyramid with medaka at the apex is formed: Phytoplankton bloom → Zooplankton feed on it → Medaka feed on zooplankton → Phytoplankton reproduce using their waste → The cycle repeats.

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 sunlight is insufficient, 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. Additionally, adding aquatic plants or Akadama soil can cause the aquarium water to become clear.
