Simulates similar water conditions to those found in "black" water rivers, hosting significant aquarium fish and plant species.

Helps simulate the onset of the rainy season to encourage fish spawning.

Provides humic substances (humic and fulvic acid), complex bio-organic molecules that increase the availability of important nutrients to plants.

Created based on research on the nutrient requirements of aquatic plants and river water chemistry.

Humic substances, naturally found in soils, are a product of the natural decomposition of organic materials.

Soluble humic substances increase the bioavailability of polyvalent cations to plants.

Blackwater rivers are characterized by the coloration of the water, ranging from light to dark brown.

The gradual increase of humic substances in aquariums encourages spawning in fish, especially for Discus and Cardinal Tetras species.

Adding the product will slightly acidify the water and decolor it depending on the dose used.

• Chemical filtration media that absorb organic material will extract humic substances from the aquarium water.
• Add 5 ml (1 cap) blackWater per 20 US gallons (75.7 L) of water once a week.
