Will Cuprisorb remove Cupramine from rocks and sand?

I've had Cupramine dosed in my 75 gallon FOWLR display tank, and I really want to remove it so that I can encourage coralline growth and invertebrates. However, I heard that you might need to REMOVE all the rocks and sand, which I don't want to do because I don't have a separate tank for the fish and all of that rock and sand was really expensive. I'm wondering if Cuprisorb in a Seachem Media Bag will remove the Cupramine from the rocks, no matter how long it takes. I do NOT want to replace the rocks or mess up the current rockscape!

 

Yes, it does. It's just recommended to keep it in there an additional 2-3 weeks than what's suggested.

 

Cuprisorb will remove the copper from your water column. The problem you are going to run into is the rocks may have soaked in some of the copper and some copper may have settled into the sand. If one of your fish was to disturb the sand bed, a puff of copper may get released into the water column. I did use Cuprisorb to remove Cupramine in a 57g treatment tank that only had PVC along with equipment, and it worked very well.

I would be tempted to leave it running in your system for awhile.

I’ll add to this a little bit. Copper doesn’t just settle on the sand bed it will actually be absorbed into the porous sand and rock. Nothing needs to physically disturb anything at all as it can leach out of the rock and the sand.
This is why wen you’re adding copper for any medical treatment of fish they absolutely tell you to test the copper concentrations often since it can be absorbed into rocks and sand out of the water column. They also recommend a bare QT tank.

With that sand and rock I would never place any inverts into that system ever. The rate at which copper will leach out is 100% unpredictable and has no rhyme or reason. For this reason I will not buy used live rock off craigslist either.

 

My understanding is that the copper will be in the rock and sand indefinitely. Not exactly forever, but for an indeterminate amount of time. Even if a test doesn’t show any copper, it may leech back into the water column at any time. You might luck out for awhile if you add inverts, but it’s likely just a matter of time before the copper leeches out again.
