Well about a week ago I noticed my blue hippo had the sure sign of ich.....white specks on his fins and sides....so I moved him to my 10 gallon QT and my LFS recommended I treat with kick-ich. Well as most of you might have guessed, the kick-ich doesn't seem to be working too well though the hippo is still eating well. While treating the blue hippo I kept a close eye on my 125g display tank and have noticed the clowns look like they're covered in dust and today have white specks just like the blue hippo did. The yellow tang has looked silky smooth each day but I have noticed him trying to scratch his sides on a rock every now and then. My 2" harlequin sweetlips shows no signs of ich, but his tailfin is deteriorating/disappearing. I thought this might be a sign of aggression from other tank mates but he's an older tank addition and is showing no differences in behavior. My flame angel, coral beauty, royal gramma, and yellow watchman goby show no signs of ich as of right now. My tank parameters have tested good... Ammonia = 0, Nitrite = 0, Nitrate < 5, PH = 8.1, Temp 77- 78. SG 1.025. My question to you all is how should I go about treating at this point? Obviously I can't fit all of these fish into my 10g QT, so should I just put the blue hippo back in the display tank and treat it all? I'm giving up on the kick-ich and by the end of the week my package should arrive that contains a UV sterilizer and Tropical Science Marine Max. As of right now the only coral in my tank is some pulsing xenia. I have been feeding just a bit more than usual and the fish have been loving it. I plan on lowering my SG down closer to 1.020 and I have not used garlic but will probably buy some soon. I have read the facts and myths about ich and wish I had a QT big enough to treat with copper but unfortunately I do not and am hoping for help from the more experienced Thank you in advance!
