Getting started

[bckane]

I ready to setup my reef tank, here the problem Im still waiting fro my skimmer Cyclone BAK-PAK 2 Bio-Filter. I want to start adding my water and mixing the salt, but I need to know how far to keep the tank away from the wall. I dont want to set the tank up and come to find out I dont have room from the tank to the wall to install the Cyclone BAK-PAK 2 Bio-Filter. Can someone measuse the distance from the tank to the wall for me so I can get started....
TIA

I would leave a 6" gap. I dont have the measurements for the Bak-Pak but 6" should be plenty of space.
