Green water is the general term used by most pond hobbyists for the pond water that is subjugated by phytoplankton or maybe more commonly called suspended algae. This type of living micro-organism is frequently mistaken as a seed due to its needs to be able to develop. The same as ordinary plants, algae mostly count on sunlight, water, oxygen and nutrients from food. They flourish the absolute most in summer time because of the warm temperature it brings to the pond water.
The warmer the water is, the considerably better it is for these creatures to develop rapidly. Through photosynthesis, the sunlight that enters the pond water is absorbed by the pigments in the algae using it to convert carbon dioxide and nutrients from food into new algae life. There are always a number of nutrients that go in and out of a water system like a pond but the mainly, algae rely on nitrogen and phosphorus. The former can enter the pond through fish wastes, uneaten food and accumulated mire in the pond bed. The latter however, is an all-natural contaminant of tap water. ABM Water Company
