I had to tear up my scape and put my fish into hospital tank today because of an ich flare up. I had Copper Power on hand as suggested, just in case it turned out to be ich. The bottle just said to add one ounce per 20 gallons for a 2.5ppm dosage, so I added it all in one go. Now I’ve seen threads where people are saying to add it very slowly over a looong period of time. Should I do a big water change right now, or roll with it? Thanks.
