The main problem is that there all more pathogens than just ich, not to mention that pathogens can be viral or bacterial.
From what i recall, although ich is dependent on a host, there are parts of its life cycle where it isnt. Ich can form a “dormant” like cyst that can be imported on LR. Ive read different things about just how long it can survive in this state, but i dont believe there is a definitive answer. I mean how many people have exhaustively studied the longevity of marine ich cysts imported with LR in marine aquaria?
QUESTION OF THE DAY!
Can someone point me to a repeatable, exhaustive, conclusive, scientific experiment that proves ALL pathogens(included ich) will die 100% in an 8 week QT with hypo, hyper, copper or whatever else. Im not a biology guy, but i think this would involve a microscope and a dead fish >LOL<
I understand the theory…life cycle…blah blah blah…kill the bad stuff at intervals to ensure eradication of pathogen at every step of life cycle…blah blah blah. As you pointed out jon, the copper can be hit or miss. How do we know, without doubt, that QT will kill EVERYHING 100%? I dont know, and im not convinced that it would. Im not saying QT is bad, and im not saying that it doesnt work, im just not 100% convinced that it does. What i am conviced of, however, is the amount of stress inflicted on a fish in a small, bare tank, treated with meds or hypo. IMO, it just isnt worth it.
Also, a point that has been overlooked, is most people dont necessarily treat a QT tank. They simply use a QT to observe the fish for outward signs of disease. This too is pointless IMO. Just because a fish doesnt show symptoms, doesnt mean it it isnt a host to a plethora of bad stuff.
So, you can use a QT to observe your fish for disease, and try and convince yourself that if there arent symptoms there isnt disease.
Or, you can use a QT to treat disease prophylacticly inducing great stress to an already stressed fish that has survived its entire life exposed to and hosting all kinds of fun stuff.
Jon, i apologize if i came off as rude. You and i have battled over this forever, im sure your use to it >LOL< No hard feelings, you know i love ya!

Surprise, surprise…i dont know everything >LOL< Im lucky if i know one half of one percent of just that i would like to know. QT, dont QT, i dont care. The biggest point im trying to make is just because an expert printed it in a book doesnt mean its right. We need to think for ourselves, the foundation of science is observation. Observe, try to repeat it, talk about it.
Look at craigs youtube clip in the octopus thread. I would be willing to be that the aquarium is staffed by “expert” marine biologists that said “sure, throw the octo in the tank, the sharks wont hurt it!” >LOL<
