## Questions & Answers

**Q: Can you put these in a firepit and simply light the rocks? No gas needed?**
A: Hi. The lava rocks do go into the fire pit. But you need to light the gas to heat the lava rocks. The lava rocks are not combustible. The lava rocks retain the heat and distribute the heat.

**Q: Could lava rocks be used for charcoal bbq please?**
A: Is the BBQ Gas? if so yes :)

**Q: Is this safe too use in a aquarium filter ?**
A: Indeed it is safe to use in aquariums. Prewash the rocks before use to get rid of the dust from the stones. We sell a huge amount to aquarium owners. Regards Peter

**Q: Can these be used below the gas burners to catch fat?**
A: I lined my fat tray with strong foil then put a layer of cat litter to absorb the fat, easy clean up after a few uses.

Ideal for the wood smoker

### ⭐⭐⭐⭐ Other half is VERY happy with these
*by S***T on 30 May 2020*

Purchased for other half’s gas barbecue. Perfect for our needs and gives our BBQs that Smokey BBQ flavour with the convenience of gas. Arrived very quickly and great value for money. Great for our needs. Chunkier than the other BBQ lava rocks we have purchased meaning they don’t slip through the grill.
