FAQs
Are these volcanic rocks safe for all types of fish?
Yes, these 100% natural volcanic rocks are safe for both freshwater and saltwater fish and will not alter water chemistry.
How much rinsing is needed before use?
It is recommended to rinse the rocks thoroughly under cool running water until the water runs clear to remove any dust or sediment.
Can I use these rocks in a planted aquarium?
Yes, the rocks provide a stable base and surface area for beneficial bacteria, and can also anchor plant roots or provide surfaces for epiphytic plants.
Will these rocks change my aquarium's pH?
No, these volcanic rocks are natural and inert, meaning they will not affect the pH or water chemistry of your aquarium.
What is the best way to arrange them in an aquarium?
You can arrange them to create natural-looking caves, ledges, or simply as a decorative base. Consider the swimming space and territorial needs of your fish.
Can these rocks be used in outdoor ponds or water features?
Yes, their natural composition makes them suitable for outdoor landscaping and water features as well as aquariums.
How large are the individual rocks?

Troubleshooting
Rocks appear dusty or dirty upon arrival.
Rinse the volcanic rocks thoroughly under running water before placing them in your aquarium or landscape.
Water appears cloudy after adding rocks to the aquarium.
This may be due to fine dust. Ensure rocks were well-rinsed. The cloudiness should dissipate within 24-48 hours as your filter clears the water. If persistent, perform a partial water change.
Rocks do not seem to be providing a biological filtration benefit.
Ensure the rocks have been in the established aquarium for at least 2-4 weeks to allow sufficient colonization by beneficial bacteria. The porous surface needs time to cultivate them.
