PSB Photosynthetic Bacteria (Home Cultured) 12L (2L x 6 bottles)

★ Listing for Mercari

Thank you for viewing.

We are offering 12L (6 x 2L bottles) of PSB photosynthetic bacteria, cultured in our home for raising medaka (Japanese killifish).

We manage by the start date of cultivation, so we will provide the most concentrated batches first.

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

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

Furthermore, the cultivation days directly reflect the price (labor cost), so we cannot offer it for less than a reasonable price.

★ Quality and Trust > Price

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

As these are anaerobic bacteria, the liquid is filled to the brim without introducing air.

If spilled, it will produce a strong odor, so please avoid opening the lid indoors upon arrival.
Please open it outdoors and adjust the volume.
