Comparison to Live Rock & Usage Recommendations
While comparable in price to natural live rock, ARKA Ceramic Rock provides a convenient alternative. It's not intended to replace all live rock but rather supplement it.

It’s recommended to use ARKA alongside natural live rock to allow beneficial bacteria to colonize the ceramic pieces. This process eventually transforms the ARKA rock into a fully functioning, biologically active part of the aquarium ecosystem.

Cave Structures and Fish Habitats
The caves included in the ARKA rock range are particularly beneficial, offering fish a safe haven and hiding places.

This addition improves fish welfare in the aquarium and enhances the overall biodiversity by providing shelter for shy or territorial species.

Material Safety and Long-Term Effects
Unlike some older ceramic alternatives, ARKA Ceramic Rock is guaranteed not to leach harmful chemicals into the aquarium water.

This ensures a safe and stable environment for your aquatic life, avoiding the potential disruption of water chemistry that can occur with inferior products. Over time, the rock will develop a natural green and purple coloration, similar to natural live rock.
