I think I have heard that you can have build up and that you need to make sure you clean it often.
Sand, like any substrate, can have buildup due to excess food, fish waste, etc. However, if you have a proper clean up crew and you keep your tank chemistry in line, then your sand bed should stay looking white and clean.
With sand, you don't have to manually clean it like you do with crushed coral. In fact, it is recommended that you don't disturb the sand bed in that manner.

Anyway how many snails or crabs do you think would do the job???
I usually try to have 1 snail or crab for every gallon of water in the tank, with my cleanup crew being mostly snails (of varying types).

Also on this board I have heard that instead of using LS because of the money and being new, that I can get playsand. I have then read online someone saying that is not a good idea?? Any suggestions??? Also the playsand will eventually become live sand correct??? (over time)
You can use playsand and it will become live over time. However, be careful not to get playsand that might leech silicates into your tank. I've heard that southdown sand (available at Home Depot) is good. One thing you can also do is along with the playsand, just buy one bag of live sand to help seed your sandbed. Live rock will also help seed your sand and help make it live.
Good luck!
