## Questions & Answers

**Q: Approximately how many pebbles are in a pack? I want to use them for a class, thanks.**
A: This is aquarium gravel, not actual pebbles. Its just called natural beach pebble because of the colour effect. There are hundreds/thousands in a pack!

**Q: What sort of volume do you get for the weight?  I'm trying to work out how much I need**
A: I used 3 bags and had a thin layer of gravel across my 105 litre tank, which is roughly 75cm in length. Hope this helps

**Q: I have a 64l tank how many bags would I need?**
A: Is the tank base circular hexagonal or rectangular because this is Prime in the calculation. If I presume your tank is 60cm long by 30cm side and you need 6cm depth of travel (to grow live plants) then you need 10 to 12kg of gravel
Please search internet for Aquarium Gravel Calculator to give you more information.
Always wash gravel before use and good luck with your project.

**Q: Can this be used for decor for a Gecko?**
A: I have a gecko but wouldn’t use these, perhaps a few big ones
