Treating my fowlr tank for ich and possibly flukes (new fish add) with copper power, just finishing a round of prazi and kanaplex. Last nite I turned the UV back on and this morning my usual totally clear water is dark and kind of orange/brown in color. Any idea what this is and how to eliminate? I don't want to use carbon as I need to maintain the copper level. I just turned the skimmer back on as well and doing a 10% water change.
