Product Details

★ Listing for Mercari

Thank you for viewing.

We are offering 4000ml (2L x 2 bottles) of PSB photosynthetic bacteria cultured for raising medaka at our home, plus 50 culture starters (not for consumption).

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

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

★ The color (hue, tone, appearance) of PSB varies depending on the culture medium (food). Therefore, the color will differ from seller to seller.
Naturally, it may differ from what you have used before.
Even manufacturer products can vary.
Please refrain from purchasing if you are particular about color (hue, tone, appearance) or are sensitive.

We only provide fully cultured batches. If we determine that we only have thin batches due to insufficient culturing time, we will cancel all listings.

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

★ Quality & Trust > Price

If you require the culturing recipe, please let us know via message.

★ Eco-Mercari便 (Delivery to Doorstep): For Kanto, Chubu, and Kinki regions (refer to guide → delivery method). If you can permit receipt, we will include 500ml of PSB or 50 culture starters.
Please check Permit Receipt before purchasing.
If it does not appear on this transaction screen, it is not applicable.

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

It has a strong odor if 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.
