I am Bubba..I have been asking all the questions about the skimmers. Mine is the pits and only works 20% of the time. I just looked at my tank and my new yellow tang has ick on both of its fins....looks like in the exact same place. Also have new Blonde Naso and he looks clean as of this second. What do I do now? Just tore down my QT tank. By the way...both tangs were QT'ed together in the same tank. "tired of mopping and tired of medicating" going to buy a lama!!! Bubba
