    All they have added is the trace elements (and only some) which any good salt mix will have in it. We look to the sand for the buffering ability and as you see their numbers are very short of aragonite.

    actually, sand and liverock have very little buffering cababilitys. the ph needs to be lower than our reef tanks to start to dissolve the substrate. [6.5 I believe?] problem with black sand is that it doesn;t reflect light very well and it'll make your tank look darker not to mention its nice to reflect some light back up underneath some corals

    JR, thought it was lower like 5.5 or 6 to be a true buffer. In any event, the higher the numbers the greater the minor amount buffering that is taking place. Huh, you just gave me a reason to re read.

    FOWLR, it really is not worth it. You'll also get a salt and pepper effect if any sediment rests on it.

    I have seen people use substraits like that for photo purposes only. They have a small tank that they put the coral into, wait for it to open up again, then take pictures of it. The colors really stand out on a dark bottom.
