    It's not the iphone pic. Usually to identify rock, I need a hand lens and be up close to see the details, unless I can see the rock in context (ie, on a the side of a formation on a cliff wall, for instance, or know where it was collected).

    I see, I got the smaller one from deep cove park, near the beach. The large one was collected near my house, behind Capilano university. I totally agree with you.

    when i was trying to find rocks i would chip the rock in an unobvious spot and then pour white vinegar on it. if it foams up apparently it can leech into your tank. if it doesnt foam, well then probably your fine. but again i am no expert but i beleive it better to be safe then sorry.

    Vinegar is acid, and will dissolve carbonates. The problem is that it is a very weak acid, so it will only dissolve the weakly bonded carbonates like calcite. It'll barely dissolve aragonite, and won't do anything to most other carbonates, which will all dissolve in water slowly over time. Having said that, it may not be a bad thing as it'll add some pH buffering capacity to your tank. Anyway, I just thought I would clarify that point a bit. If you want want to test with vinegar, 2 ways of enhancing its effectiveness is to warm it up (increase its chemical activity) or scratch up the mineral (decrease grain size).

    Probably more geology than you guys need/want to hear.

    Haha...sorry, I was saying it tongue in cheek. I actually am a practicing geologist with more years of experience than I care to divulge.
