Rocks from Home Depot

[Amphibians]

So i was just wondering if it would be allright to buy a sack of rocks from home depot and then boil them or bake them to use in a terrarium. It would be much cheaper than the pet store, plus I am having a hard time finding something large enough to not be dangerous to my axolotl.

I buy rocks from home depot all the time...just make sure you rise them well.

Rocks are rocks.....rinse them really well, as Julia said. If you are very concerned, you can bake them at 200 deg. for an hour or so.
