Yokuchi Shoka Bacteria 40g - bacteria strains derived from the natural environment

SHŌKA BACTERIA by Yokuchi is a concentrated preparation of natural nitrifying bacteria that quickly stabilises the nitrogen cycle in the aquarium. Autotrophic strains rapidly colonise filter media and substrate, reducing ammonia NH₄ and oxidising it into harmless nitrites NO₂. They ensure biological balance, clean water, and safe conditions for fish, shrimp, and plants. With as many as 5 billion active bacteria per gram, the product works effectively from the very first dose. Ideal for new aquariums, after filter cleaning, after water changes, and in the fight against cyanobacteria.

Yokuchi is a brand created from the combination of nature and science. The synergy of ecology, engineering, and passion has made it possible to create unique, professional products that meet the needs of demanding hobbyists. Yokuchi’s range includes high-quality substrates, fertilisers, and preparations that support plant growth and condition. The brand’s products are created for aquatics, terrariums, and other forms of modern plant cultivation.

Using bacteria in freshwater aquarium water is beneficial for several reasons.
First, these bacteria help maintain a healthy nitrogen cycle by converting harmful ammonia into less toxic nitrogen compounds.
Second, they support the biological processes involved in breaking down organic contaminants such as leftover food and fish waste, improving water quality.
Third, these bacteria support the development of aquatic plants by providing nutrients in an absorbable form.
Fourth, introducing bacteria into the aquarium after a water change or after adding new fish helps minimise stress and speeds up the adaptation of new inhabitants.
Finally, aquatic bacteria are crucial for maintaining balance in the aquarium ecosystem, which contributes to a healthy environment for fish and other aquatic organisms.

What is SHŌKA BACTERIA?
SHŌKA BACTERIA is an advanced bacterial preparation containing autotrophic strains sourced directly from the natural environment.
The bacteria colonise filter media and substrate in a very short time, beginning intensive biological activity in the aquarium.
In 1 gram there are as many as 5 billion active bacteria, ready to work from day one.

Main benefits
✔ Faster aquarium start-up - significantly shortens the tank maturation time
✔ Stable nitrogen cycle - reduction of ammonia NH₄ and oxidation into harmless nitrites NO₂
✔ Safe environment for fish, shrimp, and plants
✔ Crystal clear water and better plant condition
✔ Biological support after filter cleaning and water changes
✔ Effective help in the fight against cyanobacteria

How does it work?
Autotrophic nitrifying bacteria:
✔ rapidly colonise biological filter media
✔ multiply in the substrate
✔ stabilise water parameters
✔ restore biological balance in the aquarium
This is the natural foundation of a healthy ecosystem.

Dosage
Newly set up aquariums
✔ 1 g per 50 l
✔ Sprinkle onto moist filter media
✔ Wait 1 hour
✔ Start the filter

Addition to the substrate
✔ 2 g per 50 l

After filter cleaning / water change
✔ 1 g per 100 l
✔ Sprinkle directly onto biological filter media

In the case of cyanobacteria
✔ Prepare a solution:
✔ 1 g per 50 ml of aquarium water
✔ Mix thoroughly and draw it into a syringe
✔ Remove cyanobacteria mechanically
✔ Inject the solution into the affected areas
✔ Turn off the filter for approx. 10 minutes
