Substrate question

[DawgFace]

I'm planning on going black with the new tank build, Caribsea Arag Alive Hawaiian black.

First question how many lbs do you think for a tank foot print of 8'x36''? I want no more than a 2'' sandbed. On all my other tanks I just buy locally until I like the depth so I never really paid attention to the amount I was putting in. Now because of the amount I will need I'm going to order online.

Also, is this substrate too thick for wrasse?

Start with 16 bags. I think I used 13 or so in my 300, 72" x 36" and got 1.5-2" deep. My wrasses did fine in it.

I was hoping you would respond, thank you!
