ok so i am newbie im gettin a 50 to 60 gallon tank that comes with salt a filter looks like a whisper waterfall type a heater and a few other small things. i want to setup a fish aquarium and i want live rock. so i figure about 50 lbs woth of live rock right? now the part i am confused on is do i put live sand in with it or crushed corral or what? what do i use on the bottom of the tank.

Please don't use crushed coral ! It's not the best choice. It lets too much fish poo accumulate in it. Use sand ! Also if you haven't read my substrate 101. Please check it out.
