[Extra Concentrated] Medaka Fish PSB Photosynthetic Bacteria 600ml Free Shipping

Thank you for viewing!
This is Extra Concentrated PSB (Photosynthetic Bacteria) cultured daily with care by an enthusiast who deeply loves Medaka (Japanese killifish) and Southern Red Cherry Shrimp.

I use this PSB extensively in my own Medaka breeding, maintaining clear, beautiful water and healthy fish as shown in the 6th image.

- PSB Photosynthetic Bacteria: 600ml
(Delivered in 2 x 300ml pouches with caps for easy handling)

[Main Effects of PSB (Water Purification & Nutrient Supplementation)]
- Decomposes harmful substances like ammonia and odor-causing components in the aquarium, stabilizing water quality.
- Contains abundant nutrients beneficial for Medaka's health, such as Vitamin B12, carotene, nucleic acids, and ALA (aminolevulinic acid).
- Serves as a valuable early nutritional source for Medaka fry (babies), helping to prevent starvation.

[Strict Measures Against Bursting & Leakage]
To minimize the risk of bursting due to environmental changes (temperature and pressure) during shipping, the pouches are not filled to the brim, leaving a slight buffer.
Furthermore, the pouches are placed securely in Ziploc bags and shipped in a double-protected, Nekoposu-exclusive cardboard box (see images 2-5).

*In the unlikely event that the product arrives damaged (leaked) due to unexpected impact during shipping, please contact Mercari's Damaged Arrival Procedure (Mercari shipping insurance) before leaving a review. We will respond sincerely through the Mercari support team.

[Shipping Timing]
We strive for speedy shipping to get the product to you as soon as possible after purchase. (We will notify you if there are any delays due to unforeseen circumstances.)

[Easy Culturing Method - No Failures Even for Beginners!]
*Due to the live bacteria, there is a unique smell (like sulfur). We recommend wearing rubber gloves when handling.
1. In a thoroughly washed plastic bottle, add 50% or more of this concentrated PSB.
2. Add commercially available Ebios tablets (2 tablets for 500ml, 3 tablets for 1000ml is a guideline).
3. Fill the plastic bottle to the top with tap water directly from the faucet (ensure no air is left).
4. Close the cap, shake well, and place in a location with ample sunlight.
5. In about a week, you will have rich, concentrated PSB! I have never failed using this method myself.

We are committed to careful packaging and a pleasant transaction. Thank you for your consideration!
