Setting up a quarantine tank

[edikpok]

I was just wondering how to setup a proper quarantine tank.

I have my main 29g biocube and I have a 10g tank that I use as a quarantine. I currently have a coral beauty sitting in the quarantine tank (it's been a wee... and no any signs of anything bad).

So my question is: how long should I keep the fish there? should I be treating them? should I change the salinity?

Thanks!
