Is this substrate good?

Is sugar size sand ok?

And is it gonna fly everywhere or stay put?

Don't know for sure . Like I said I found a sand that's safe and used it . You still have all that rock that is going to eventually damage it to think about. I'll stick to a fw ray and just a plain empty tank of sand . It's not going to work in saltwater with live rock unless it's a huge custom tank . That's all I can tell you .

I'm going to stack the the rock on the sides. It's says it ray safe.
