I'm NOT a fan of dosing to correct Iodine/Iodide/Iodate (there are technically 3 forms) for a few reasons.
One, you have to test for all 3 which is a royal PITA
Two, Iodine derivatives are poisonous to invertebrates in too high a concentration which is easily reached via mistakes
Three, maintaining proper levels has never been shown to have benefits to livestock health over low levels
Last, waterchanges easily replace it without worrying about overdosing
