How do I bring down the copper level in my tank besides water changes?

Is FritzCoppersafe the product to use for this or does ACO sell a product?

I think Coppersafe /adds/ copper to your water, not removes it.  If my googling is correct.

 

I can't think of a not crazy way to remove copper without just changing water.

You could try a chelating agent and activated carbon.  or pumping it through an NSF-53 filter.  The NSF standard only tests lowering 3ppm copper to <1.3ppm, so IDK how well it actually works if you want less copper than that.

 

Actually google says seachem makes a resin you can put in your filter:

Thank you! I don't think carbon removes it.  I just thought there was a product out there that reduces it chemically.  Thank you!
