Thanks for all the replies and great input. I'm over two weeks in on a copper treatment, so I'd hate to change it mid coarse to hypo and have a setback. I just need to dial in the amount of drops I need to maintain the .5 after each water change.

I put the garlic soaked seaweed into the tank this morning and he seemed very enticed, but I still didn't see him eat any. That's not to say he hasn't when I wasn't around. The soaked seaweed made a mess though, so I need to find some that will stick together. Good thing I'm doing a water change today ;). SF, you mentioned you don't have an issue with your nori falling apart, which you purchased from HEB, which brand did you get? On a positive note, he seems to be a little more active, so maybe it's just a matter of time before he indulges.

I'll keep you posted.
