Recommended for home culturing as well. There are some tips for culturing. A common method for culturing PSB is to add 3 to 4 times the amount of tap water to the starter culture, add food such as Ebi-os tablets, and wait for it to concentrate in sunlight. However, this method may raise concerns about the time it takes to culture and the possibility of culturing failure.
Therefore, we recommend culturing only what you need. Place the purchased PSB into a container that can hold the amount you bought (a container that can be filled to 80% capacity). Use it as is. Once the amount decreases to about 70% to 60%, add 3 to 5 Ebi-os tablets and tap water to fill the container, and place it outdoors or in sunlight. It will be a little diluted, but the effect is sufficient. As you use it, it will gradually become more concentrated and return to its original concentration within a few days. When it decreases to about 70% to 60% again, add water and Ebi-os tablets in the same way.
This cycle is recommended because you can use it immediately upon arrival, you don't have to wait for culturing, and it's easy to manage. Please give it a try.
