Dude that is a lot of sand! I used 120ish in my 120 and have a 3" bed in most places, deeper in some and less in others. One nice thing you wont have to go out and buy sand to replace as it vanishes out of your reef.
LOL...I used the SB calculator on Fantasy Reef and got 267lbs for 4" SB plus two extra bags for fuge. I just double checked it thinking I may have entered the wrong dimensions but its correct as long as it is an accurate calculator. Didnt know sand disappears or perhaps settles but hey, like you said, I have some top-off now
