Eheim LAV Biological Filter Media 1L (1010g)
The main task of biological filter media is to provide optimal conditions for bacterial colonization, allowing a stable bacterial lawn to develop quickly. These bacteria feed on organic particles and convert harmful substances into less harmful forms, helping maintain clear and healthy aquarium water.
After the initial mechanical filtration (e.g. using EHEIM MECH or MECHpro), biological filtration becomes essential for stable water parameters and long-term water clarity.
EHEIM LAV Natural Volcanic Rock
Composed of natural volcanic rock, EHEIM LAV features a rough, highly porous surface that supports extensive bacterial growth. This structure ensures efficient breakdown of organic waste and improves water quality over time.

FAQ
What makes Eheim LAV different from other biological filter media?
Eheim LAV is made from natural volcanic rock with a highly porous, rough surface that supports dense bacterial colonization, enabling efficient breakdown of organic waste and stable water conditions.
Can Eheim LAV be used in both freshwater and saltwater aquariums?
Eheim LAV is designed for freshwater aquariums. It is not recommended for saltwater systems due to potential compatibility issues with saltwater environments.
How long does it take for bacteria to establish on Eheim LAV?
Bacteria typically begin to colonize Eheim LAV within a few days after installation, especially when used in conjunction with mechanical filtration and regular water changes.

I’ve used Eheim LAV in my 50-liter freshwater tank for over six months. The water has stayed very clear, and I notice less fish waste buildup. The rock is durable and doesn’t break apart easily. It’s a reliable choice for biological filtration.

The porous surface works well for supporting beneficial bacteria. I combined it with my MECHpro filter and saw a noticeable improvement in water stability after two weeks. Easy to install and maintain.

After switching from a cheaper filter media, my tank has become much cleaner. The Eheim LAV maintains consistent water quality even during feeding cycles. No clogging issues so far.
