So in the store with the 10 year old daughter recently, she really wanted to get one of these pieces with the "swimming hole" carved in it. Doesn't exactly match the LR
we have but hey, it's really her tank so we got it.
Now I've done a search of course and have found many threads about "lava rock". Some saying avoid it for fear of metals, some saying it's fine.
Petco's web page for the product claims "Safe for all aquarium habitats". Can we trust that? We definitely want inverts eventually.
Thanks in advance,
