Aquarium Advice FINatic
walking through home depot yesterday looking for pool filter sand, i came across the tile section. so i bought some thinking it would be cool to be able to custom make slate caves whatever shape i want. upon further reflection, i thought maybe the slate has been treated or polished with something unsafe for my fish. the guy at home depot says no, it's all natural slate. but looking at it i noticed the man-made grooves on the bottom of the tile and can't help but think he's wrong.... anyone had this dilema?
