Base Rock

Hi;
Can Volcanic Rock be safely added as a base to the LR in a cycling tank ??

Thanks,

Dan

depends on what is in that rock, have you tested them for Iron, and heavy
metals, for a start for toxic things... ?

Not sure if there's any truth to this, but when I added volcanic rock to my
tank (back when it was a fish-only tank) I had an increase in nitrates ...
one of the LFS said it was caused by the volcanic rock, so I took it out.

I know another fish owner who used tufa (sp?) rock as a base rock with
success ... personally, I used live rock throughout.

No, so far I'm just toying with the idea. How do I test for all that?
Thanks, Steve

I have made a lot of base rock from crushed coral and a concrete mix. I had
to "rinse" the rocks in trashcans in the yard for about a month before the
levels came to 0 but it works great and super cheap. (for $20 you can make
about 100 pounds). And I also use small pieces to start frags on, most
that is exposed in my tank now has coraline on it and you cant tell the
difference. You can find recipes on the net.

The composition of the rock varies. Some fist stores sell rock that has
been tested.

Hi Dan

Do you mean 'man made lava rock? "The book of the marine aquarium" by Nick
Dakin advises that Lava and Tufa rock are the best rocks to use in the
aquarium (besides live rock...). Volcanic rock would of course be high in
contaminants such as sulphur.

I've had issues with Tufa before as it wasn't as easy to clean as I first
thought...

Regards

Chris

not easy in the home. if you don't know its safe, then play is safe, we
all
have too much money involved in out tanks to take risks.
