I have been reading alot on various sites about homebrewing and on several I saw suggestions of adding a Iodophor solution to the airlock. I took this advice. I poured a couple of drops into the cap and dumped it into the airlock, then filled with water. I dumped most of this out and refilled to the line to dilute it. After sealing the fermenter I pressed down on the lid alittle and it sucked about 1/3 of this iodophor solution into the beer. Should I be worried?
