Are they reactive, as in causing pH and/or kH to raise/drop? Pour a bit of vinegar on it, if there's bubbling, don't use it.
i just bought a few piece of rock which is stated as sponge rock over the LFS.
is a white colour with pinkish look and had many holes and crevice, smooth.
only now i m thinking whether this type of rock is suitable for planted tank.
12g planted tank
22g low ligh planted discus tank
4g fish only marine tank
never say never to start a new tank....if got enough money
