well here in europe (the netherlands to be axact ) ionide is not approved so the the only waterpurification tablets we can get here are cholerine tablets ( or drops ) like the Katadyn Micropur tablets, so we don't have packeging problems round here with corosife ionide tablets. Personally i perfer aquaclear tablets or puritabs in my PSK, since the come in foil packeting witch is easyer to pack, but they aren't aproved in the US...<br>
