About algae balls?

When algae balls are cultured, well water or lake water can be used inside, and tap water from water pipes cannot be used directly. The frequency of changing water does not need to be too fast, once a week in summer and once every two weeks in winter. It can be placed in a place with poor light every day. Be careful not to breed with other small fish and shrimp when breeding. Marimo is a freshwater algae species in green algae, so it can be cultivated with tap water and changed to fresh water every night for about a week. You can also add some green algae nutrient solution to it, so that its algae branches will become more and more lush. The water temperature should be kept below 25℃, and the lower the water temperature, the more helpful it is to the ecology of Chlorella. If it is too hot, you can cover it with a cork and put it in the refrigerator. In the process of culture, it is necessary to avoid the direct sunlight of Chlorella. Indoor light or any artificial light source can make Chlorella grow normally. Under careful feeding, Chlorella will keep growing every day, with a speed of about 5mm a year. During the growth process, there will be green algae with branchlets around the algae ball. As long as you pay more love when changing clean water and gently smooth the green algae along the algae ball, the green algae will grow into a natural ball healthily. Just like fish farming, only more subtle than fish farming. Everything needs to be done carefully, because they also have lives that need to be respected.
