Light is the first requirement to bring water plants in the aquarium from four sides to the water on the grass, so that the light intensity in the aquarium is opposite to the natural waters of the lower light intensity.

At the same time, different water plants have different demands on light intensity and exposure time, and light needs good growth.

Such as Newtonian grass, red butterfly love flowers, large leaf grass, pearl grass, red chrysanthemum and so on, these species of aquatic plants during the daytime lack of sunshine, the night use the fluorescent lamp to prolong the time of light.

Weak light can grow well, eg. Greengrass, orchid grass, sunset peppergrass, green chrysanthemum, etc .; Such plants can not be placed directly in the sun, the cover should be used for their shade.

Between the two plants, such as foxtail, European crown grass, etc., they only have to accept sunshine in the morning and in the evening.
