Adding Live Sand to Established tank.

[hummer]

I've had a barebottom tank for a while now and was thinking about adding a shallow sand bed (approx. 1"-1.5"). I bought a bag of Aragamax Select Sand. Any suggestions on the best way to add the sand and keep all the inhabitants happy?
I have a 90g w/ 33g sump. approx 90lbs LR, hammer coral, bubble coral, sps, zoas.
1. Turn off pumps and powerheads.
2. Rinse sand?? (fresh/salt water?) <- LFS says I could rinse it first but I'm not sure if that will ruin the sand.
3. Slowly scoop sand in.

Thanks for any suggestions.
