Product Details

★ Listing for Mercari

Thank you for viewing.

We are offering 8000ml (4 x 2L bottles) of PSB photosynthetic bacteria, cultured for raising medaka at our home, along with 50 culture starters (not for consumption).

This is equivalent to 25 bottles (12.5L) of PSB, using 2 starter tablets per 500ml of PSB.

PSB is managed by the culture start date, so we will provide you with a concentrated, aged product.

★ The color of PSB varies depending on the culture medium (food), so the color will differ between sellers.
Naturally, it may differ from what you have used before.
Even products from the same manufacturer can vary.
If you are particular about color or are sensitive, please refrain from purchasing.

We only provide fully cultured products, so if we determine that the culture period is insufficient and only thin products are available, we will cancel all listings.

Furthermore, the culture days are reflected in the price (labor cost) at a minimum, so we cannot offer it for less than that.

★ Quality and Trust > Price

If you need the culture recipe, please let us know via message.

★ Eco-Mercari Delivery (doorstep delivery): For Kanto, Chubu, and Kinki regions (for details, see Guide -> Delivery Method) → If you can permit receipt, we will include 500ml of PSB or 50 culture starters.
Please purchase after checking the Permit Receipt box.
If it does not appear on this transaction screen, it is not eligible.

As this is an anaerobic bacterium, the liquid is filled to the brim without introducing air.

It has a strong odor when spilled, so please avoid opening the lid indoors upon arrival.

Please open outdoors and adjust the volume.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
