i tryed paraguard wich didnt seem to help i also hypo'ed my tank wich seemed to get rid of the ich (too late for the puffer,cowfish and flame angle) and i ended up with a large nitrate and bacterial infections problem wich killed my lionfish however the 6 doller domino damsil and free yellow tang did live thanks to hypo,garlic and zoe
sorry had to vent about burying my tank
i recomend getting the copper as fast as you can
