Elemental copper?
Folks,
I've got a pond that is partially overhung by a big faux-thatched roof that is capped/covered in copper sheeting. Copper has been there since about 2002 and is well weathered/green. When it rains, water pours off this roof evenly in all directions, including into the pond.... A massive rain might put 5% roof-water into the pond/system.
a) is aged elemental copper a particular problem? Loaches and FW stingrays are on the stocking list.
b) if so, are there chelating or filtering agents (charcoal?) I can/should fit into the filter system?
Thanks,
A

I don't know if run-off rain water would pick-up any traces of copper, but maybe standing water would. It probably depends on the acidity of the water. A copper test kit would probably tell you if it does. It sounds like the copper is oxidized, so perhaps the oxidation layer will prevent it from leaching also. I'm not sure though.
Activated carbon might not remove copper.
You'd need to use "E.D.T.A. (Ethylene Diamine Tetra Acidic Acid) to chelate it out of the water"

Ditto: Chelating materials will remove many metals, including copper. Activated carbon probably does not. There are also filter inserts that will remove copper. If you want to filter that water before it lands in the pond you might look into these products.
I would not trust water from that source.

38 tanks, 2 ponds over 4000 liters of water to keep clean and fresh.
Happy fish keeping!

Can you do some testing of the runoff before you have to scrap the idea and see just what the levels are? maybe get a sample when it first starts raining and one during mid downpour and see if the levels are actually high enough to pose a threat. I'm thinking that just like with copper pipes that once they get that initial layer on them they are pretty harmless.
I'm wondering more about the possibility of the loaches ending up as stingray snacks???
