Media Type	Porosity	Durability	Best Use
Porous Rocks	High	Medium	Large tanks with strong flow
Lava Stones	Very High	High	Natural aquascapes and biofilters

Plant-based Media

Plant-based media uses natural fibers to support bacteria growth. These materials also help absorb some toxins and improve water clarity.

• Made from coconut coir, peat, or cellulose
• Biodegradable and eco-friendly
• Works well in low-flow tanks
• Needs regular replacement

Chemical Filtration Choices

Chemical filtration helps keep multi-species tanks clean and healthy. It removes harmful substances from the water that mechanical filters cannot catch. Choosing the right chemical filter media is key for different tank needs.

Here are some common chemical filtration options. Each works in a different way to improve water quality for your fish and plants.

Activated Carbon

Activated carbon is a popular choice for chemical filtration. It adsorbs odors, discoloration, and toxins from the water. This media works by trapping impurities on its surface.

• Removes chlorine and chloramine
• Reduces organic waste and odors
• Clears yellow or brown water tint
