Self-cultured PSB (Photosynthetic Bacteria), approximately 270ml surplus.
Comes in a pouch bag with an easy-pour cap.
Can be used for medaka (killifish) and plants.

For aquariums...
Food for medaka and fry, water quality management and purification.
For vegetables and gardening...
Liquid fertilizer, soil improvement, disease prevention, growth promotion, etc.
Can be used for a variety of purposes.
Priced affordably for trial.
Can be cultured and increased with Ebiōsu tablets, water, and light.

As it is cultured with Ebiōsu, there may be some sediment, but it can be used after shaking. (The color in the image may differ slightly from the actual product.)

Culturing is less likely to fail if you use a higher ratio of PSB.
Example: When making with a 500ml PET bottle, fill the PET bottle about halfway with PSB, fill the remaining half with water, add one Ebiōsu tablet, slightly crush the PET bottle to release air, close the lid, place it in a sunny spot, and shake occasionally.
*It has an odor, so be careful not to spill it.
*There are various methods for culturing and usage, so please check online or elsewhere.
*Will be sent via Yu-Packet Post Mini (envelope).
*To avoid exceeding thickness limits, it is filled to approximately 270ml. It is made stronger than usual.
*Shipping fees, handling fees, and raw material costs account for a large portion, so discounts without reason are difficult.
*For bulk purchases, we can offer a discount equivalent to the shipping cost. Please let us know in advance.
