Volcanic rock???

That's what I've always heard also, heavy metals in
Volcanic Rock plus some other undesirable minerals.

The real issue here, although I'm not that concerned, is the leaching of heavy metals
which bothers some reefers.

and the coralife doesn't.

Does the Ca get released into the tank?
I'm the one with the Ca reading of 600 while using NO additives. Not
that I imagine that will last once I get more corals.

been a volcano. There is rock there that looks very much like some
live rock, very porous and open but dark coloured.

I need way more rock in my tank but am happy to add dead rock and
wait. How can I find out if I could use this stuff? I know there
have never been chemicals of any sort used over there and the only
possibility of anything like that contaminating it would have been
if cattle were dipped for ticks in the yards about a kilometre away
and went straight there, which they don't, still dripping (not
really possible in our dry climate).

Is it possible it is a test error or test kit issue ?

Well I might have thought so if the RO water wasn't testing 0 and a
petshop didn't get the same result. One day I will get round to testing
the tap water (straight from the creek). By the time I test all my tanks
(FW as well) I get sick of testing. My nearest marine pet shops are all
2 1/2 hour's drive away in 3 different directions

I've tested and tested. There is meant to be a colour change from pink
to blue. Mine only changes to dark purple at 600 really. I can get to
higher if I try to go for the exact shade of blue and that is in front
of a window with good light. At 580 the sample is still bright pink.

One thing though. I have some sort of algae or seaweed thing gowing
well. Not overtaking but it's looking quite good. It's bright green and
sort of cactus shaped, like a zygocactus but it is hard. I'm wondering
if it would need Ca to thrive and maybe that is why it is thriving. The
tang doesn't touch it as far as I can tell. Visitors love it and think
it is planned - I don't enlighten them

Yep, it takes up a lot of calcium. When it dies, it will
be white as the sand.

That's the stuff alright. Only a couple of pieces have broken off and
died. I was told it is illegal to dump this stuff in the ocean here. Not
that I intended to but a fellow reefer just passed the comment. He said
it can become a nuisance.

For the most part, the government does no want anything
put back in the wild, especially if it is not native.

Under ideal conditions, it can grow quite fast, but it's
very easy to remove in the aquarium. In the ocean, it
actually can contribute quite a bit to the sand/substrate.

Leaching from where to where?
Sorry but I'm really not up on this stuff (as if you couldn't
already tell that )


From the rock to your water. The risk is from introducing something
NOT from the ocean (the volcanic rock) into a reef tank. The level of
risk depends on whom you ask, and actual content of the rock, which
is difficult to determine outside a geologists' lab.
