Aquaforest Lava Soil 5L is a premium natural aquarium substrate made from volcanic lava and enriched with essential minerals for aquatic plant growth. It provides a stable foundation for planted aquariums while gradually releasing nutrients to support healthy root development and vigorous plant growth. The substrate is pre rinsed for convenience although slight cloudiness may occur initially which naturally clears within a few hours. Its mineral rich composition supports long term plant nutrition making it ideal for aquascaping and freshwater planted tanks. For best results it is recommended to limit additional fertilization during the first months to maintain nutrient balance.
