I recently bought a house that have 6 outdoor ponds. I bought about 10 koi, gold, moor fish. Two of my fish died I think it's from ich. They have white on them. One seems realky sick. I went to the pet store yesterday and bought Api.ich cure it's a tablet. I put one I yesterday and one today and I haven't seen anymore dead fish yet. Does anyone know how to easily get rid of ich? I'm not an experienced fish owner so this is all new. Please help. Thank you.
