You also want to make sure that the rock will not affect the hardness or salinity of your tank. Rocks containing calcium (limestone, coral etc.) can leach hardening the water. Rocks containing salt crystals (potash etc.) will turn the tank saline. Good choices are most igneous rocks like granite. IP: Logged |

An easy way to test for calcium is to put a little vinegar on the rock. If it fizzes, the rock will leach calcium into the tank and increase the harness. -Chelle IP: Logged |

That will work if your rock is the same throughout (homogenous). If not, you'll have to dip the whole thing in vinegar. For salts, let it sit in a bucket of water for a few days and see if it becomes pitted or dissolves. If you have the test kits for you aquarium anyway, just drop them in a pail of water for a week and then measure hardness and salinity - then you'll know for sure. IP: Logged |

hmmm...I did the vinegar test on shale and nothing happened - although it was advised (strongly) that I not use it for the reasons above anyhow....it's really not worth it if you have a lot of fish- or fish that you would not want to risk losing. I heard slate is okay. IP: Logged |

If they told you not to use it because of Ca content I would have to say they're wrong. Shale is basically compressed mud and silt. It may contain some mineralized phosphorous and could conceivably contain particles of other minerals, but it is primarily made up of fairly inert particles. Monteray Bay Aquarium has a shale reef display. IP: Logged |
