Found this information related to laterite on on of the international planted forum. this table shows that copper content in laterite(at #25) is 218 mg/Kg. so would like the inputs of all the members on this.

Simply yes.

Also consider the solubility state of copper(atomic or by salt in sample?) in it. Then do a % by weight calculation from the given ratio in water volume of your tank. Or you want me to do calc let me know.

I thought it is safe. I am keeping shrimps in latarite from years.

Here you go pal! Did some digging for you, and you owe me...


Its found in form of metallic Cu alone in laterite.

Cu literally doesn't react with water, but will do with oxygen+moisture. UNLike iron it doesn't corrode further.

Even if it does corrode to form CuO.

http://en.m.wikipedia.org/wiki/Copper(II)_oxide
Solubility of CuO

Solubility in water
insoluble

Solubility
soluble in ammonium chloride, potassium cyanide
insoluble in alcohol, ammonium hydroxide, ammonium carbonate


So literally no chance for Cu to affect the livestock.

Cheers! And merry Christmas!
