QT of mature fish for large tank

[kvosstra]

HI guys,
Setting up a QT for 5 larger tangs from a mature system (500 display) - tank has ICH and, when the tank is moved, I will do a full QT for the system - fishless for 45 days, and then a full QT, both for ICH and internal, just to be clear. I am planning on using a 90 gallon as a QT, so the fish have space.
My plan is 14 days at 2.0 ppm copper using copper power; plus focus and general cure (though I am pretty sure they are free of these parasites, I'd rather be certain).
Transfer at 14 days to another 90 g and running General cure externally (or prazi pro). I'm having trouble finiding all medications - A m a zon seems to have, but I'd rather use a focused business, if anyone has a recommendation...note, a package for QT would be a nice bundle at a store .

1. My plan is to make the two 90g tanks identical for purposes of hiding spots. At 14 days, I will catch fish in a specimen tank and transfer to the new tank - what is the best way to minimize transfer of copper water/ICH water?
2. I'm having a hard time seeing how much medication I need for this setup. Assume that the existing fish will go through this 90 gallon QT, simply because of size. I plan to otherwise use a 20 or 40 breeder for future quarantine of new fish. The tank needs a lot of fish, it's pretty empty right now. so, simple question - how much copper power, focus, general cure do I need?
3. once I use the one 90 with copper - should I assume that the tank will always have copper? Or can I re-use it as a frag tank in the future, after some cleaning process (bleach/ammonia?) or do I need to run carbon in this?
4. Should I use dividers in the 90g to separate the 5 mature tangs? Obviously, this will be a lot smaller than their usual 10 ft display tank?
5. Ammonia badge - I have 2 older ones, one used, one still in package...do they still work (like 5 years old), or just buy new?

Thanks!

Youll want to be fishless for 76+ days. Most do 90 to be safe.
Unless im missing something why 45 days?

New post in this forum about 45 days being safe, as compared to the old 76 day requirement.

hmm, there's a lot there in your post.

you'll want the display to be fallow for 76+ days

1) the best way to transfer fish from one tank to another is to catch them safely then use a plastic colander, it's way better than a net.
2) Read the labels, do the math. One large bottle of copper power should be enough. General Cure, 1 box, treats 100g at a time. It takes 4 doses. So, you'll need 4 boxes.
3) No, you can remove the copper. You'll need to clean it super thoroughly. A search on r2r will detail how to remove it all. It's important to not keep anything like rock that will absorb the copper.
4) I did, just smaller scale. Egg crate worked great.
5) They work ok-ish. Your best bet is to use a salifert kit and test daily.

I picked up the QT tanks on Friday. They need a little cleaning, but will be ready to go soon - working on organizing the basement now to get all tanks organized for the QT process, and to get the main display ready too! So much going on to get a huge tank moved and installed...
