Detecting and Removing Copper from Water

On my 10g tank I am trying to keep it as native to the region as I can for the materials (plants, rocks, driftwood, substrate, etc). However, I am slightly concerned about the amount of copper that could be contained within the substrate and rocks. What would be the best way to test for copper? Should there be copper, what would be the best way to treat it?

You can buy copper test kits. If there is copper in the rocks and substrate the only way to treat them would be to remove them.

LaMotte makes a low-level copper colorimetric test kit (compare a reacted solution to a chart) that claims to go down to 50ppb (0.050ppm).

Copper is an interesting element for aquatic life - it is toxic to algae at lower levels than that which is toxic to fish. It also is known to bioaccumulate in molluscs (snails) - hence its use as a snail killer - and fish and amphibians. However, it is an important trace nutrient as well.

To get more precise and to measure lower levels of copper, a much more expensive instrument/test would be needed - the LaMotte test will give you a ballpark. It would work well for finding out if a particular rock is leaching copper into the water column.

Finally, carbonates, organic matter, and some clays help remove copper from the water column through precipitation and adsorption.

copper test kits?
What's the difference between copper test kits and super scanner metal detector?
Dose cooper test kits have more functions than metal detector?
I am so curious.
