Yep, should be fine. It's supposed to be from 1.5 to 2.0 lbs per gallon for optimal filtration but youre in the range.
are you going to add any live rock at all? that can make up any difference in rock if you wanted to go on the heavy side.
I personally plan on about 120lb in my 90g, I want an open tank for that build. But I usually go heavy on the rock elsewhere. lol I have over 200lbs in the 125g and am gonna add another 50lbs as soon as I get around to moving it from the floor in front of the tank!
