Please tell me this is not ick.

Are you raising the temperature? If so, getting it up to 86 will be lethal on it's own. If not, gradually adding another cup will be safe--more than that and you'll want a means of testing. There are some very thorough guides to treating ich with heat and salt here in the Diseases forum, as well.
