Substrate for plant aquarium Dennerle Soil Black Color Type 1-4mm 4l

This is a nutrient-rich substrate designed to promote strong plant growth. It contains all the essential minerals and trace elements and features fertile volcanic soil. The substrate also has a biofiltration function, ensuring healthy and clear water. It actively creates a soft, mildly acidic environment (approximately pH 6-6.5, KH 0-2 °d). It is double-fired, providing long-lasting stability.

Ideal for use in combination with CO2 fertilization, it includes valuable humic and fulvic acids. Suitable for plants, fish, and shrimp that require soft, slightly acidic water, this substrate is perfect for bottom filters due to its specialized nutritional formula, which prevents algae formation. Its ability to lower pH and KH values, along with its filtration properties, makes it an excellent nutrient substrate for the growth and breeding of various shrimp species, such as Red Crystal and Red Bee.
