From what I saw, the special grade is much bigger sand particles...bigger than I wanted and I didn't want the color. It's supposed to be engineered for nitrate issues but from what I saw I think they all are right? The best pic up close I could find was this:
As mentioned below with the blowing etc, that's why I went with the 2:1 ratio mixed. I like the look of the sugar but wanted to cut down on any blowing. I have two korilia in my tank now and they set low and it hasn't caused any issues. I still have a half bag of each so if it does I will simply put a thin layer on top since my tank is new and the bed isn't alive yet. I went with around a 2 inch bed this time because its easier for me to clean. My live rock is the base for my biological. Not sure if you knew this but my tank was bare bottom for a few months. Everyone told me not to remove my deep sand bed because I would have issues but I did it and never had even a tiny spike. Don't get me wrong, deep sand beds can and are beneficial however after a few years I find that they can become a source for nitrates regardless of how well you vacuum. Just an opinion.
