any live sand will do, depending on where you are, the sand may cost $0 for 20 lbs, but that could be more or less, as for the jaubert system, i would use a dsb, it is just as effective, and alot less ork to replace and to set up, just build a 4" sand bed, and seed it with a bag or 2 of live sand, that eaasy, as for the cycle time, it can take months and months, but generally only a couple of weeks, if you use ls(live sand), it may only take days, but this is all depending on your system, just be prepared, it could take up to 2 months, the best thing to do, IS DO NOT HURRY IT, let it ride and it will go faster, doing water changes and adding things to bring down teh ammonia will only set it back instead of letting it run through, some lfs's will have you do things to bring it down, DON"T, but i don't see it taking months and months(however if you want to let it, and wait that long, you are better off than the rest of us, being that you will not over wait, this cannot be done, nad never let anyone hurry you when you want to wait, only in diseases should you hurry)
. But at least I have something larger to move into. Please look at my next topic re: The Jaubert System.
