I just came home tonight to see all of my fish now have ich and looks like their fins are getting destroyed. My neon pseudo is barely hanging on for dear life. I only have 4 fish currently and none are attacking each other. I recently added carbon to my sump and all of a sudden I have foam in my tank and my skimmer is filled with white foam. Please help I do not have a way of qt the tank my corals seem fine though.
