Anybody know what type of wood this is? And is it safe to use? Saw good ones being sold really cheap. The owner uses them for his aquariums so I tried one and it doesnt seem to harm anything. Its releasing some kind of brown poop-like stuff tho but thats it. Heres a pic from my phone. The wood is redish-brown.
