Volcanic rock???
 

I'm not a geologist and don't remember much about what I was taught at
school on the topic but my hubby tells me that over in the far back
corner of our farm is an area that a geologist told him had 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).

Volcanic rock is very porus, but it has nothing else to
offer. Best to stick with light weight calcium based rock.

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.

Thanks Wayne

Hi Miskairal: We have on part of town here in Ks that the city water comes
from a lake that must have a high calcium concentration. People there never
add Calcium to there tanks it comes with water changes. maybe that is why
your calcium is so high. lucky you.

Yes, some water supplies can be very high in Ca. We have had a few on the chem forum with
this issue/problem

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

The calcium does disolve some, mainly from things digging
in it. Criters can't dig in lava rock. There are some
creatrus that take sulfur from the water and produce
sulfuric acid, and slowly etch into the calcium rock. Some
createrus chew their way into the rock. This is natural,
and good. Lava rock does not offer this. Denitrification
seems to take place better in calcium base rock and sand,
than silica based rock and sand. I can't say for sure what
the difference is, but it just seems to be be better,
maybe it's the buffering ability. Maybe it's available
minerals. I don't know, it just seems better to me.

OK, that all makes sense. A shame as I never would pass up something
that is free :)
Thanks for the explanation.

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

Afraid that's not the case. I use RO water and the Ca is 0 in that. It
reaches 600 as soon as I add the coralife salt, before it goes in the
tank. I've tried other brands of salt but they have phosphates present
and the coralife doesn't.
