Reef Flakes or Special Grade?

[Miami Reef]

Currently I have nature’s ocean in my high flow tank, and it’s blowing and shifting like crazy. I’m going to the wholesaler tomorrow and need some advice quick. Which sand is more heavier in which it won’t move, shift, or blow?

LOL. I'm getting rid of my Fiji Pink and replacing with Special Grade right now. FP looks great, but what a pain. It blows around too easily and it's a diatom factory.

Special grade is great haven’t tried reef flakes.

Just bought 120lbs of special grade. Let’s see how it looks. I’ll update with a picture
