. If you want to make green water with tap water, you need a container first, because it takes some time to make it, during which you can't add water and drain water at will, so you must determine the amount of water you need at the beginning, and then choose the right size container according to this. The opening of the container should be larger, otherwise it will affect the exchange of oxygen. It should be noted that because the tap water has not been trapped, it can not directly produce green water, it needs to be dechlorinated first.
. The essence of green water is that the water body contains a large amount of Chlorella, which can not grow without illumination. Therefore, in order to promote its rapid reproduction, it is necessary to place the container of water in the sun and expose it to the sun all day, which can accelerate the explosion of algae and make the water body green. It should be noted that the normal fish tank can not be so exposed to the sun, the sun time is too long, the temperature is easy to rise, the temperature difference between day and night is too large, affecting the health of fish.
Of course, it is not enough for green water to rely on light alone, but also need proper nutrition, so it is necessary to fertilize water. Fertilizer is also easy to get, just use the dirt at the bottom of the fish tank, which is usually the residual bait that the fish did not eat and the feces it excreted, rich in organic matter, and the ammonia nitrogen produced after decomposition is the nutrition of algae.
