PSB (Photosynthetic Bacteria) 500ml Pouch x 2 Bags

I enjoy keeping goldfish and killifish as a hobby ?
I feed them PSB daily, and they are growing very healthily.
I have some extra because I've cultured too much, so I'm offering it at a low price for anyone who wants to try it or wants to culture it themselves ☆
This PSB is more concentrated than commercially available products.

It is said to have effects such as increasing the survival rate of fry, culturing rotifers and daphnia, promoting growth, enhancing coloration, decomposing and removing feces and uneaten food, decomposing malodorous components like ammonia, hydrogen sulfide, and short-chain fatty acids, promoting the proliferation of beneficial microorganisms like actinomycetes, stabilizing water quality, purifying water, supplementing natural vitamins, and improving immunity.

The ingredients of PSB are natural amino acids, natural vitamins, L-arginine, and taurine, with no artificial coloring used.
For homemade culturing, I use empty carbonated water plastic bottles and add a culturing agent (Ebisu tablets).

It will be shipped in a pouch-style nylon bag for easy transfer.
I will put more than 250ml in one bag and ship two bags ?

For culturing methods, I will include instructions and 20 culturing starter tablets as a bonus with your shipment, so please try culturing it yourself ☆
If you wish to change the volume, please leave a comment.
