Perlagro Lava rock is a great media for drainage and water retention.

Lava rock has neutral Ph. It can be used many times at hydroponic culture after washing.

Lava Rock Usage in Agriculture Industry:

  1. In land reclamation
  2. In plant cultivation in less soil or soilless environments
  3. In agricultural – green areas with limited water feeding.
  4. Hydroponic & Aquaponic Growing Systems

There is no weed problem. Thermal temperature control around the root equally keeps it from growing, protects it from heat and cold. Keeps the oxygen rate high around the root. Provides healthy root formation. This provides the plant to grow more vigorous. It is useful for water economy, prevents evaporation of water, creates low energy costs. Provides higher quality water to the roots. It provides faster growth of microorganisms that make the nitrogen in the soil water-soluble so that the plant can take it. Long-lasting structure (arrangement of soil grains) Resistant to insects, fungi and plant diseases. It does not contain any toxic substances to plants, It is homogeneous, easy watering Low salt content Having a certain cation change  It is very rich in chemical minerals.

Aquarium lava rocks are volcanic natural substrate for aquascaping aquariums.

Highly porous volcanic rock
The highly porous volcanic rock has various tasks in an aquascaping aquarium: First, it provides a stable base for further constructions of stone and / or wood (roots), which would slip further down through the soil. On the other hand, many beneficial bacteria settle in the porous structure, contributing to a positive water environment. Furthermore, the porous rock structure provides a good penetration of nutrients and provides many minerals, allowing plants to root and grow very well.

Great Products and Reasonable Prices

It was shipped fast, the packaging did not allow damage. If you need substrate for your fish tank this is what you need to start. Just be aware of chunk size. No complaints.

Looks like a viable alternative

Bought this to use as a substrate in an aquascape I am planning. I was looking for JBL Volcano Mineral substrate but it has been out of stack across the UK since last September. Technically this looks a viable alternative although the granule size is much larger (JBL is 4 - 8mm) however the judicious use of a lump hammer and some seiving should resolve that. Twenty kilos is much more than I need but it may come in useful for the garden. Perhaps producing a product of smaller particl size and perhaps bags of 5 and/or 10 kgs is a new market opportunity for Black Rock? The Aquascape sector is really struggling to get something to match JBL

Hi Rodger, Thanks for taking the time to review the product and your suggestions of a new opportunity for the Lava rocks. This is something that is being discussed currently and hopefully another product in the Lava rock range will be added soon that fulfils the Aquascape sectors requirements. I hope you have a great day. Regards, David
