Photosynthetic Bacteria PSB (Home Cultured) 4000ml (2L x 2 bottles) ⑦

★ Listing for Mercari

Thank you for viewing.

We are offering 4L (2L x 2 bottles) of PSB photosynthetic bacteria, cultured in our home for raising medaka.

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

★ PSB color (hue, tone, appearance) varies depending on the culture medium (food), so the color will differ from seller to seller.
Naturally, it may differ from what you have used before.
There are differences even among manufacturer products.
Please refrain from purchasing if you are particular about color (hue, tone, appearance) or are sensitive.

We only provide fully cultured products, so we will cancel all listings if we determine that we only have thin ones due to insufficient cultivation period.

Also, the cultivation 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 cultivation recipe, please let us know via message.

★ Eco-Mercari便 (Delivery to door): Kanto, Chubu, Kinki (for details, see Guide -> Delivery Method) → If you can allow receipt, we will include 500ml of PSB or 50 culture agents.
Please check Allow receipt before purchasing.

As it 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 after arrival.

Please open outdoors and adjust the volume.
