Fertile water
The purpose of fertilizer water is to cultivate beneficial algae, reduce the transparency of water bodies, stabilize water quality, and also inhibit the growth and reproduction of moss. In the 2-3 days after the fertilizer has been watered, as long as the conditions allow the pond mouth can grow green algae or diatoms, the water color is green or tan, which is a change in the algal phase, which can be judged by water microscopy to determine whether there is algae growth and reproduction.
After the use of some fertilizer aquatic products, the color of the water body has changed, darkening into brownish yellow, which is likely to be the addition of coloring things to the fertilizer aquatic products, such as: sodium humic acid, potassium fulvic acid, etc., which can not only fertilize the water to cultivate beneficial algae, but also reduce the transparency of the water body, which is conducive to inhibiting the growth of moss in winter and spring, which is beneficial to early fertilizer water, and is also conducive to the rooting and growth of aquatic plants.
There are many breeding friends think that after using fertilizer water paste or other fertilizer aquatic products, the water color must be changed, after use of the color immediately becomes dark brown, this idea is not accurate, if the product is added to the sodium humic acid and other color substances, after the fertilizer water can make the water color deepen, reduce the transparency of the water body. There are some fertilizer aquatic products that do not add coloring products, after use, the water color will not change, but the use of fertility to promote the growth and reproduction of algae, two to three days after you can see the change of water color, microscopic observation of algae growth and reproduction. If we just want to reduce the transparency of the water and let the water have a color, we can choose to use sodium humic acid, potassium fulvic acid or other coloring products can change the color of the water body, reduce the transparency of the water body, there is no need to reduce the degree of water by using fertilizer aquatic products.

The purpose of fertilizer water is to cultivate beneficial algae, and once the algae are cultivated, the purpose of fertilizer water is achieved.
