150 fowlr with ich and velvet?

I have a 150 gallon Fowlr which managed to break out in ich. I must have missed it on one of my fishes while in quarantine. My purple tang also looks to have marine velvet. now i know in order to get rid of it i have to quarantine all fish and leave the display tank fishless for 8 weeks. This is going to be a little bit of a problem due to the amount of fish.

I currently have
4"purple tang-signs of marine velvet
2.5" sailfin tang-looks ok
2" niger trigger-looks ok
2" porc puffer-slight signs of ich on fins
6" lopezi tang-looks ok
2.5" flame angel-looks ok
3" lionfish-looks ok
2" maroon clown-looks ok

Now my question is how should i quarantine all these fish. Currently i only have a 20 gallon quarantine set up. should i break these fish into 2 tanks or should i get a 55 gallon and put them all in there with a bunch of pvc to lessen agression. Im also afraid of putting all the fish into the quarantiine causing a ammonia spike. What is the best way to go about this and what should i treat the fish with? I have cupramine and a seachem copper test kit.
 
I would be tempted to go for the 55 + lots of PVC and stuff like some plastic plants (!). Use the filter from the current QT and put another in to start maturing, and maybe do some largish water changes for the first week or so while the filters get going properly, like 10 gallons daily and then redose the copper on top after that..

I'd go for copper myself. Good luck.
 
I had tried copper in the past with good success. However, just becareful with the Tangs as copper had been know to damage their digestive system.
good luck
