Rewd, Most likely the worst you heard is a hobbyist main tank has ick due to a new fish in their tanks and it lead them to many problems causing them many other of their fish to died as well. This however is due to many types of fish, such as the blue tang and we all know how hard it could be to place one in our main tanks and all we can do then is to cross our fingers and pray.
If I for one of my larger reef tanks once it all begins, was to get this blue tang, I will leave a few easy corals with a cleaner in the 40 QT, and I for as long as eight weeks will add nothing else to this QT during while its holding the blue tang. I mean, I wont even allow my skin to touch the tanks water, I will ware gloves.
This is like the time when I known of this other person overseas. He gotten himself the blue tang and his tank was a 65 gal tank and he had a skimmer like the very first one every build that the skimmer sets in your tank. I told him that he had no business getting himself a blue tang for his not the tank for it.
But three times his blue tang gotten ick and the first two times he listen to me and I told him pacific things what to do and one was for the next 6-7 weeks, he would add nothing to this tank and the reason his tang gotten ick each time was he thought that he could add some corals or so because he said the tang was looking happy. I told him that when I said that he can add nothing to his tank, it meant nothing and I even gone through lengths to told him to try not to put his hands in his tank. But when his tang gotten ick the third time, he didn't try to listen to me in trying to help it again, and after that, he qui ted the hobby.
Also, I know of a good number of people who use no QT and the trick to their success is not to be in any hurry for one thing. And in preparing their new fish arrivals very slow and slowly. Still myself, now even more so due to that I will be doing three large reef systems, I will need a QT even more than I ever did before.
Only once in my whole life in this hobby did I have to treat a main tank and ever since then, I took precautions not to have to do go through that again and being for having a reef tank, that method of treatment is out of the question.
Grins & Niko, im still in waiting and while waiting, im planning for I just this past week was hit hard with my propane delivery of 250 gals and it cost me $758.79> OUCH!! Im still looking to begin after the starting of the new year the new (old) 150 gal tank, I spoken to Kevin and he knows that I will have him switch over all of the LR and sandbed over to the 150, a long with the lighting.
