I transfered over the course of a week or so, didn't do the switch all at once.
I will add this,( and its just my opinion as Allen Repashy hasn't replied to my pm yet)
krunch didn't do as well as my others. But we all know he has health issues.
I think this is a great all in one for healthy chams. I now add a little additional rep cal calcium to his. But this is just me, not suggesting others to do it. You need to know your Cham and what he/she needs with this and all other aspects.
But I do love this product and I have ordered the vit a and superpig as well
