Another cupramine question

[kaiboshi]

So I treated my fowlr dt with cupramine sunday evening. I'm a bit confused though, I thought that copper killed all inverts yet I see not one but three dwarf hermits that I missed when I removed my inverts that are still alive and well a little more than 48 hours after the initial dose. I'm a little baffled because I lost one of my dwarf lions (supposedly copper sensitive) but there are three hermits still alive? Is it possible that my lr and sand absorbed the copper completely or something and that the ich killed off the lion?

I'm not sure how I should proceed at this point, I'd like some advice. The idea of setting up two smaller tanks is one I didn't consider, maybe I can arrange it. Should I start to run mad carbon and cuprisorb in my dt and set up some hospitals to start the copper over again or has the damage to the lr/sand already been done OR should I continue treatment as is?

edit: no discoloration of lr/sand/water/anything thus far, no bleaching either. Don't know if that info helps with the decesion to move to another tank or not. I'd think at this point it may be the best option instead of adding more carbon.

I put a fish in QT awhile back, and i thought to ease his pain i would throw in some cheato too. It came with snails and pods of course. I dosed the recomended amount of cupramine (for the first 48 hour period i think it was) and then when i was about to dose again i noticed some dead snails, but more alive snails.

Long story short, i went with hyposalinity instead! 4 weeks later its looking good so far.

You need to get Seachem's copper test kit. Sometimes LR and sand will absorb some copper and you will need to redose, so you'll need to know how much you need to redose by.
Test kits by other brands don't work well with Cupramine. For example, my API kit completely fails with Cupramine.
