Red Lava Rock per LB (5cm-15cm)
Red lava rock is a porous volcanic stone commonly used in aquariums, aquascaping, and biological filtration setups. It’s lightweight, inert, and safe for both freshwater and marine systems.

Inert & Aquarium-Safe
- Doesn’t raise pH or hardness.
- Safe for planted tanks, shrimp, community fish, cichlids, and aquascapes.
Highly Porous
- Excellent surface area for beneficial bacteria colonization.
- Helps maintain stable biological filtration.
Great for Plants & Aquascaping
- Ideal for:
- Creating terraces and elevations
- Use as a base layer for planting
- Anchoring epiphytes (Anubias, Buce, Java Fern)
- Root systems grip easily due to its texture.
Lightweight
- Easy to stack
- Less stress on glass compared to heavier stones
