RE: Lava Rock
Hi RJ
I was wondering on any 'anecdotal' info on the list on
what is working, I am quite familiar on the 'live
rock' as I make, culture and sell live rock :-)
Visits to Rochester pet shops will let you see a lot
of it in the better shops although you may have to ask
which is which.
My question/concern on the lava rock is that being of
volcanic origin it will have different compositions,
and may well have metallics/salts that could leach
out.
Has anyone had a problem with this? Seems it would be
wise to presoak it and rinse a few times before using?
