Lava Rock

[victimizati0n]

Straight from my book:

Lava Rock: Natural volcanic rock is not recommended for the marine/freshwater aquarium as it contains very heavy metals and toxic substances. The lava rock supplied to the aquatic trade is often a by-product of the smelting industry, sold as totally inert and safe. However, there have been reports of toxic impurities in lava rock, and a reputable source of supply should always be used. Safe lava rock makes excellent homes for invertebrates and fish alike. It is light, porous, displaces very little water, and locks togerther well into safe structures. On the negative side, lava rock is very expensive, has dangerously sharp edges, and is usually incapable of being worked. It has no pH buffering ability whatsoever and may even be slightly acidic.

Sorry but what book is this from?

Could you post the name of the book, the author, the publisher and year it was published please?

In 20 some odd years of being an aquarist that explaination is the most odd I have ever seen.

I checked through roughly 3/4 of the books I own or use at work (6) new and older. None of them say anything remotely similar to what your book says.

I even contacted our Fellerstone rep, but she has not gotten back to me yet.

I suspect that the book is one of the older press issues of aquaria that maybe has not been updated. I have a couple of older books that say some really strange things because at the time that was the best possible explaination. IE using meth blue for ich ????

Even some the more recent books have some glaring errors of one sort or another.

Sorry victimizati0n no insult intended but I just don't believe it.

ok even if your book says "The lava rock supplied to the aquatic trade is often a by-product of the smelting industry, sold as totally inert and safe." So now isn't this the lava rock that were talking about???

anywho any rock that has metal in it won't be good in a Fish tank and any rock with sharp of jagged side could be harmful to the fish, but it still doesn't mean its not safe.

blitzen25bm where did you find you lava rock in HD what section.

i use any lavarock i can find; the landscaping ones or even the ones for bbq grills.

i once remember when i built my pond about 8 years ago i had big pieces of lavarock that sounder pretty similar to what it was talking about and the holes and grooves in it were really big very pourous and i dont remember where it came from.
