In order to make the fish tank grow moss, we must first ensure that the water body has a certain fertility. At ordinary times, we can increase the amount of bait, increase the residual bait and feces in the water, and make it eutrophic. Secondly, it needs some light. Moss cannot grow without sunlight. If the light is insufficient, it is not easy to grow moss, but it will promote the reproduction of brown algae. First, how to make the fish tank grow moss? To make the fish tank grow moss, we must first ensure that the water body has a certain fertility, and we can increase the feeding amount at ordinary times, so that the residual bait and feces in the water will increase, making it appear eutrophic. Secondly, it needs some light. Moss cannot grow without sunlight. If the light is insufficient, it is not easy to grow moss, but it will promote the reproduction of brown algae.

Second, what are the benefits of growing moss? 1. Purify water quality: The growth of moss itself shows that the water body is eutrophic. In this case, the high content of ammonia nitrogen in the water will be harmful to the health of fish. With moss, it can be absorbed, which can not only avoid fish poisoning, but also provide nutrition for itself, so it is equivalent to purifying water quality.

2, provide feed: moss itself is also a good food in the water, because most fish are omnivorous, so you can eat moss, as a green feed, but also has certain nutrition. However, it doesn't mean that you don't need to feed moss. The nutrition of moss is not enough, but also needs some water fertility.

3. Increase dissolved oxygen: As a plant, moss itself contains chlorophyll, so it can carry out photosynthesis and release a certain amount of oxygen. Increasing dissolved oxygen in water is very helpful for fish to breathe, but it is only effective during the day, and lack of light will consume oxygen at night.
