【Includes Instructions for Cultivation and Management】 Instructions for using, maintaining, and cultivating green water will be provided via the transaction message after purchase. This is 500ml of magic water, green water starter, essential for raising medaka fry, juvenile fish, goldfish, and koi. Dilute it with dechlorinated tap water or aquarium water. What is Green Water? Green water refers to water that has turned green due to a large bloom of phytoplankton. Strictly speaking, green water is water that has become greenish due to the proliferation of floating diatoms. Effects of Green Water 1. Decomposition of Harmful Substances As mentioned, green water has a large bloom of phytoplankton. Nitrates and phosphates contained in fish waste are a constant problem in fish keeping. However, by using green water, phytoplankton absorb harmful substances as nutrients, effectively neutralizing them. For general fish keeping, you would purchase a filtration system to artificially adsorb harmful substances. By using this green water, you can reduce those costs. 2. Becomes Food for Medaka Medaka are omnivorous, but in nature, 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 top is formed. Phytoplankton bloom → zooplankton eat them → medaka eat the zooplankton → phytoplankton reproduce using their waste → back to the beginning. By stabilizing this cycle, medaka are unlikely to starve even without artificially feeding them special food. Precautions Plants perform both photosynthesis and respiration during the day. However, on cloudy days or when there is insufficient sunlight, only the oxygen in the water is consumed, leading to oxygen depletion for the medaka. This can rarely occur if the green water is too concentrated, so weak aeration is necessary. Additionally, adding aquatic plants or Akadama soil may cause the aquarium water to become clear.
