What therapeutic level do you use? I have Cupramine on hand, do you think that would be too harsh on them? What do you do about the sandbox? I have extra sand, for TTM I was going to give it a fresh sand box with each transfer. I was worried about copper being absorbed into it and leaching back out.
Regarding what level to use, I was reading a post by Seachem support... the employee said that while .2-.35 works to eradicate ich, you would need more in the range of .4-.5 to kill flukes. I'm not sure about how I feel about levels that high with a leopard, even ramping up very slowly. But, theoretically if I did it would take care of either issue... where TTM will only help with crypto.
I'm just trying to weigh the risk vs. gain here, the fish aren't doing terrible considering, I'd hate to lose any of them :/
