Marshal island live sand???

[handzoff]

Hello I will be ordering my 7 lbs of marshal island nano live rock this week and was going to purchase the bagged live sand but then I noticed that you have some marshal island live sand in. What is the size and color of this sand is it full of bacteria and maybe other life (pods worms etc...) Is it going to help boost my ph. I guess my main question is, is it better than the bagged stuffand what color is it? Could you send me a picture? Thanks
