Ultum Nature Systems Controsoil Black

A quality planted aquarium substrate provides the foundation for healthy plant growth. Ultum Nature Systems Controsoil is a natural blend of soil and volcanic ash. Setting it apart from other substrates, Controsoil does not contain high nutrient levels that can cause spikes in ammonia levels. It primarily focuses on impurity absorption and providing balance from the start. This approach makes UNS Controsoil a great choice for all skill levels and allows anyone to create a beautiful aquarium.

Controsoil is available in various granule sizes and colors to accommodate user preference and aquatic plant choice.
