Your thoughts on "Ich-Free" tanks - IS IT POSSIBLE?

[NastayNatron]

Ok. I would like to know what you guys are doing for quarantining new arrivals. I want to know if you guys think it is actually possible to keep a completely ich-free tank. My tank has been up and running for about 5 months now. It is a 125g display with fuge and sps/lps/zoos, a Crocea clam, etc. I have about 12 fish in the display right now. EVERY single fish that has entered the display has undergone Cupramine treatment and came out of quarantine Ich-Free. I Set up the tank with ALL brand new sand, 100 Lbs of never-used dry Macro rock. I seeded the tank with rock from a tank that ran fallow(with out fish) for 8 weeks. I dip all coal with Coral Revive by two little fishies before they hit the tank. I have never seen ich in the display but today I think I may see 4 or 5 dots on my blue tang. Now keep in mind I followed all precautions to prevent ich. The only way I could see it entering the tank would be on a frag plug? There are so many myths out there in forums that its almost impossible to get a hold on ich. I know it is possible to keep a completely ich-free tank, but I want to know how many people actually do it and how you do. There is no possible way to make absolute sure ich does not enter without TREATING-not just quarantining(our eyes may miss something) every single thing that enters your tank. Every LFS I have ever been too has at least one fish with Ich. It is clearly in all of there systems. Please let me know what your thoughts are and what your quarantining methods are. Also include how long your tank has been running the way it is and if periodically you notice ich present(cysts on fish or flashing every once in a while). I can't imagine everyone keeps this parasite out of there tanks.
