Converting to DSB questions

Ok, she is really thinking about converting to a DSB of LS! Hip Hip Hooray!!!!!!!!!!
First, my info: 80 gallon tank, Fluval 404, Prizm skimmer, powerheads, heaters, yellow tang, 2 domino damsels, 4 clowns, 1 striped damsel, 1 3-striped damsel, 2 crabs, 2 cleaner shrimps, lots of snails (but need more).
My questions:
1) How much sand (dead initially) will it take to get a 4" DSB? Assume 20-40lbs of live sand will be bought from the LFS.
2) What type of dead sand should I get? I know about southdown, but am wondering what "type" of sand is it? What should I look for on the bags?
Ok. Please answer those questions and anything related to it.
Here is my thoughts about converting:
A) Buy some large pails and place the fish in them with a powerhead and heater.
B) Remove the live rock and decorative items and place in another pail with powerhead and heater.
C) Remove the cc and ls mixture and place in old rinsed stockings (good use for her old stockings) and place in another pail of water from tank.
D) With half of the water probably out of the tank, place new dead sand in tank. Seed top of sand with 20-40lbs of ls.
E) add lr back (and some of the decorative items). Place the cc stockins on on sides. Place powerheads in.
F) after cirulating for awhile and letting sand settle mostly, place fish and inverts back in tank
Sound good? Please answer my questions too!
Thanks!

I went through this switch in my 75 gallon about 9 months ago. What a messy project. Ended up with an ammonia spike for about 10 days. I did the stocking filled with the CC from before the switch, I also used about three 40 pound bags of AragAlive live sand, and still had the spike. After the first 10 days, and daily water changes, etc, things are AWESOME! The tank is MUCH healthier now than ever before. Well worth the hassle. I know that many people have done it without getting a spike at all..
Good luck!

The formula for calculating pounds of sand is :
Legnth of tank x width of tank x desired depth (in your case 4) x .0579. Good luck!

Thanks for the formula. It looks like I need 200lbs of sand.
Nickbuol, how long did it take you to do the switch?
Thanks!
