This depends on what is causing the fish to be "sick." If it is Ich for instance, you don't want the LR
in there for most ich remedies.
To answer the original question, I would put the filter media in the existing tank and grow the beneficial bacteria there. Then after a month or so transfer it the new tank. Meanwhile, you may as well get going on the new tanks biological filter on its own, if you already have it.
Is there any other established media in your current filter you can use without disrupting your current tank?
