BioLava is a mixture of porous volcanic rocks used as a substrate and bedding for aquatic plants in water reservoirs or a component of biological filters in ornamental garden ponds. It provides excellent conditions for the development of aquatic plants, and in aquariums it can additionally be used as a decorative bedding. BioLava is characterized by a large surface area and a porosity of up to 47%.


  1. Promotes the growth of aquatic plants and develops healthy root systems;
  2. A pure natural mineral mixture with a fraction of 2-16 mm;
  3. Does not change pH and CH parameters;
  4. Absorbs ammonia and nitrogen compounds;
  5. Contains a lot of micro and macro elements;
  6. For use in all types of water reservoirs;
  7. An excellent substrate for biofilms;
  8. Substrate porosity of up to 47%;
  9. The product is sold in a 25 L bucket;
  10. Available in large 1 m3 bags on request;
  11. 1 m3 of substrate weighs 820 kg.

Usage: soak well, then mix with sand and clay. Spread the resulting mixture over the immediate vicinity of the roots of a plant. A 25-liter package is sufficient for about 10 m2 of the bottom of a water reservoir. This substrate can tint the water and light colored gravel, so it is recommended to completely cover BioLava with washed BioKalonit. In bathing ponds, bentonite should be used to protect BioLava from direct contact with flowing water.



The high porosity of the mixture provides a favorable habitat for large amounts of beneficial bacteria that support the filtration and self-purification processes of water.

The substrate for aquatic plants includes: volcanic aggregate, chabazite-type zeolite, and volcanic lava with a high mineral content.

The volcanic zeolite contained in BioLava inhibits the growth of algae and removes toxic ammonia from the water. Volcanic lava is an ideal substrate for the roots of aquatic plants.

BioLava ingredients are obtained only from selected and tested volcanic deposits of the highest quality and purity. BioLava is currently the best substrate for aquatic plants.

Recent research shows that volcanic lava can release some phosphorus into the water. Phosphorous is essential for the proper growth of aquatic plants, but excess phosphorus can cause algae growth.
