Bio-Rocks Media
High surface area provides the optimal environment for beneficial bacteria to colonize. With all of the surface area but 25% less weight than lava rock (and half that of gravel!), expanded clay Bio-Rocks are the more stable, less abrasive alternative to heavyweight bio-media.
- Lightweight and stable.
- Durable and easy to clean.
- 5-Year Warranty.
One box of Bio-Rocks suits the BG2234 Media Bag.
