Has anyone tried Starblast blasting abrasive?
It is described as follows: "Starblast™ blasting abrasives are a loose blend of uniformly sized coarse and fine staurolite sands that have clean, rounded surfaces. There are three grades: Starblast™, Starblast™ XL, and Starblast™ Ultra."
I like the look of it, but I do not know if it is aquarium safe. Does anyone have any experiences with it?
