I'm picking up a 150g tank this weekend. Its going to be 72x18x<> I think its around 29" tall, but I dont think that should matter.

I want to do a deep sand bed -- 4 to 5" at least. How many lbs of sand should I pick up? Should I get "dead sand" and seed it with garfs grunge, or does it really matter to get that much live sand?

I have a 45g and 65g tank that I'm going to be taking the sand bed out from and dropping it into this new 150g. There is probably a 2" bed on both of those tanks, and they have been established now for about 9 months.

So, should I just pick up a bunch of regular dead sand and use the sand from my two existing tanks to seed it?

I have couple of buckets of aragonite live sand that I have from my 180. If you need them I can make you a deal or trade for coral.

A propper DSB should contain different grades of sand mixed (like a mix of
