Porous Structure

• Promotes biological filtration by providing surface area for beneficial bacteria 
• Helps maintain water clarity and supports the nitrogen cycle.

pH Neutral & Inert

Root Support for Plants

• Ideal for planted tanks: improves root oxygenation and prevents compaction

Aesthetic Appeal

Versatility

• Can be used as a base layer or mixed with other substrates.
• Suitable for shrimp tanks, betta habitats, and nano aquariums.
