can someone teach me lol.

[Nano]

Hey guys, still no sign of any ich in my clown all though I'm sure he is still carrying. I am setting up a quarentine for adding any future fish to the tank I am going barebottom with a few lbs of LR. My question is hyposalinity, how do I do it? What's considered a good level for hypo and how should I go about acclimating the fish to it? Obviously I've never done this before so I'd like a bit of help. Since I'm only adding nano sized fish I have just got a 10 gallon that I've been waiting to set up for this.
