Dying Shrimp, New Plants

[Shred]

Hi all I've just bought some new plants from my lfs, I have 3 amano shrimps and one bamboo shrimp in my 100litre tank. I put them in and the shrimp seemed fine however after around 2 hours I popped out for 30 mins and when I came back I notice 2 of the amanos lying on their backs near the front of the tank. I'm guessing its some sort of copper poisoning from whatever they treat the plants with, so I immediatly got a bucket and took some water from my bettas tank and put them in there. It took me a while but I also got the other amano and the bamboo shrimp, both seemed quite drowsy but weren't on their backs like the other two.

What can I do?

Water changes and run some fresh black carbon.
Also add some fresh filter matting or floss.
Increase aeration.

I've been running the carbon since for about a week now. Should I remove the carbon now and add some new stuff in? And is it safe to add the shrimp now?

Anyone? Please? The shrimp don't like being in with my betta!

After a week the carbon will be well and truly spent, take it out, do a 50% water change and put the shrimp back in.

I wouldn't have bothered moving the shrimp, I would have just done a 50% water change and put the carbon in with the shrimp.

Thanks for the reply, I'll do that and add some new carbon just to be safe.

And I didn't have any carbon on hand to begin with so I had to remove the shrimp.
