Re: Clams: How Do I Know... Croceas' top out at aroud 5" I hear.
Im not sure on the Iodine thing... A lot of refrences to minmal dosing with lugol's. But I don't have any hard core info either way. I have not payed any extra focus on Iodine in my clam tank in well over 9 months... that is not to say it is the right way to go.
