*Features: Easily create a "black water" environment similar to the river environment of tropical rainforests.
- 100% natural humic acid.
- Despite being humic acid, the product maintains a neutral pH of 7.
- Made from natural peat, ensuring safety and peace of mind.
- With a pH of 7, it is almost neutral and does not cause rapid changes in acidity.
- Supplies humic substances optimal for aquarium environments.
- Because of its high concentration, a small amount of addition can ensure brown water (black water).
*Uses: For keeping tropical fish from the Amazon River and Negro River systems; for Betta fish; for stress relief and color enhancement; for promoting health and spawning of aquatic creatures; for healthy tropical fish keeping; and for mitigating heavy metal toxicity through the buffering effect of humic acid. *Usage method: Add 2.5ml of this product to 10L of aquarium water and stir well.
*Dilution ratio... 4000 times. *Due to high concentration, a small amount will color the water.
For 4L of water... 1ml; for 10L of water... 2.5ml; for 20L of water... 5ml; Small aquarium: 10L... 2.5ml; 30cm tank: approximately 13L... 3ml; 45cm tank: approximately 30L... 7.5ml; 60cm tank: approximately 60L... 15ml; 90cm tank: approximately 90L... 22ml; 120cm tank: approximately 220L... 55ml. Please replenish regularly (every 1-2 weeks).
- After use, close the cap and store in a cool, dark place.
*Product specifications: Humic acid content: approximately 7%; pH: 7.0; Raw materials: Peat (lignite). *Extracted through a chemical process.
Country of origin: China. *No expiration date is set, but please use within one year.
*Caution: For freshwater use only.
- Since it neutralizes metals, it is not suitable for keeping mollusks that require metal detoxification.
- The humic acid contained is a fine particulate substance and will be filtered out by filters, so do not use a filter during application.
- Zeolite, mackerel stone, and activated charcoal also absorb humic substances, so avoid using them simultaneously.
- Some aquatic creatures may not be compatible; start with a small amount and observe.
- Be especially careful when using with sensitive fish and shrimp.
- During use, monitor water quality through testing and manage accordingly.
- It is difficult to remove if it gets on hands or clothes, so handle with care.

Recreating the natural environment with black water O-O-(O-O) Black Water Base was developed to reproduce the river environment of the Amazon rainforest.
It is rich in tannins and fulvic acid, creating a natural water quality.
Provides an optimal environment for tropical fish, ancient fish, especially Betta, Arowana, Discus, and supports their health.

Maintains stable pH 7. This product contains humic acid but keeps the water nearly neutral at pH 7, preventing sudden acidity changes in the aquarium.
This creates a gentle environment even for sensitive tropical fish and reduces their stress.
Maintaining natural water quality supports the health of aquatic life over the long term.

High effectiveness with small amounts: 300ml of concentrated solution can produce 1,200 liters of black water.
Because it can be diluted 4,000 times, it is effective even with small amounts of use.
Economical and long-lasting, reducing breeding costs.
Suitable for a wide range of tanks from small Betta and medaka tanks to large aquariums.

Ideal for promoting the health of tropical and ancient fish: This black water not only recreates the natural environment but also promotes the health of aquatic life.
Tannins and fulvic acid supply essential minerals to fish, contributing to growth and spawning.
Especially effective during breeding periods for Betta and Arowana.

Activates microorganisms to improve water quality: Black water promotes microbial activity, improving water quality in the tank.
This stabilizes the environment, providing a comfortable habitat for fish.
Microbial activity purifies the water, allowing water quality to be maintained over a long period.

Safe and easy to use: Add 2.5ml of O-O-(O-O) Black Water Base to 10L of aquarium water and stir well for simple application.
Regular supplementation maintains an ideal black water environment.
Features easy use even for beginners.

Proper use of filters and adsorbents: Even with powerful filtration or adsorbents, adjustments are necessary to maintain black water.
Adjust filters to prevent humic acid from being adsorbed, ensuring long-lasting black water effects.

Provides a safe breeding environment: Black water mitigates heavy metal toxicity and offers a safe environment for aquatic life.
Especially for sensitive fish and shrimp, start with small amounts and monitor water quality for safe use.
Flexible enough to accommodate even difficult-to-keep fish.

Long-term storage and stable quality: Made from humic acid extracted from natural peat, maintaining stable quality over time.
Store in a cool, dark place to ensure long-term usability and always provide fresh black water.

Easily recreate the Amazon River environment: Using Black Water Base allows you to easily reproduce the natural environment of the Amazon River in your home aquarium.
Utilize natural power to enhance the health and beauty of aquatic life, making fishkeeping more enjoyable.
