Hey guys, I'm probally gonna convert som Fina for this winter..... I am just waiting for my 2 cartons in the mai l and the gonna get 4gkit from research kits. now my problem is that i am concerned with the sterility issue....... I got my instructions from gotfina.com on how to convert it.....now my question is if i follow all the directions including bakin it in the oven..... should i be safe ? go and figure that there's BA in the solution so that should steralize it to some degree..........also i am reading post abou using a coffee filter how the hell are you supposeto use it.... the instrutios at gotfina.com say nothing bout a cofee filter...any help would be appreciated
