PSB Photosynthetic Bacteria 12L (2L x 6 bottles) + Culture Medium 60 pcs

★ Listing for Mercari

Thank you for viewing.

We are offering 12L (6 x 2L bottles) of PSB photosynthetic bacteria, cultivated for raising medaka at home, along with 60 culture starter packs (not for consumption).

This is equivalent to 30 bottles (15L) of PSB, with 2 tablets per 500ml of PSB.

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

★ The color (hue and tone) 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 commercial products show variations.
If you are particular about color (hue and tone) or are sensitive, please refrain from purchasing.

We only provide fully cultivated products. If we determine that the cultivation period is insufficient and only thin cultures are available, we will cancel all listings.

Furthermore, the cultivation days are reflected in the price (labor cost) at a minimum, so we cannot offer it at an excessively low price.

★ Quality and Trust > Price

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

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

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