Is this type of lava rock safe? http://www.walmart.com/ip/Backyard-Gril ... k/19581246
It says its used as a radiant, but I don't know what that means or if its a normal lava rock but treated with something... idk.

lava rock is actually pretty rough on fish. have you considered a trip to a land scape supply store in your area? i prefer to have a variety of rocks to choose from . just my opinion but i wouldnt use it. GL to ya

The only thing that lava rock is good for is in a shrimp tank. It grows a biofilm on it that shrimp cant get enough of it.
