Picked up some lace rock treated with copper. How do i clean? - Page 2

I read it in one of my reference books somewhere (I can try to find it) that .1ppm is where copper becomes lethal to marine inverts.

to me, even partial poisoning and the resultant stress from undetectable levels of copper are just putting your critters at a disadvantage.

when you can test for the MAXIMUM harmless level of copper to all inverts, then the rock would be good. dont you think once you are approaching lethal, you are already in a really bad place?

i dont think your tester has that resolution either.

zero is not zero. zero is less than some real number. below that number, you just dont know.

brute force solution: dont use the rock when you dont know the real leach levels

For example if you have the salifert copper test, you are able to test copper levels of .05, .07, .1 and up. So basically if copper is registering at all just play it safe and don't use the rock or the aquarium in question for inverts. This is not rocket science.

if copper is registering at all,
don't use the rock.

Now that I'll agree with!

No worries, i took it all back to the LFS and got a store credit yesterday.

Also, If a rock i picked up from thier base rock shelf that is like "stark freakin white" is that the basalt rock your talking about? or just some random colored white base rock?

Base rock should look like this.

This is the 2 pieces i have i was questioning.

Bump

Have you heard about the vinager test?
I think you soak it in wmite vinager and and it fizzes and anything that's left over after a while is impurities.
You'll need to read up about it to be sure.

Even different events from a single vent can have totally different mineral composition. Although I have seen some rock labeled "lace rock" which was a limestone, but usually its basalt.

I was hoping you were going to jump into an explanation of Fractional Crystallization....I was a Geology major in college

Basalt is usually a gray to black mafic rock..due to high concentrations of Iron and Magnesium and low concentrations of Silica, sodium, and dissolved gas.

I've already secured them (tonight actually) to my foam/rock wall. So we will see what the parameters turn out to be when i start up the tank.

Thanks for the info people!
