Sounds like what you have found will be fine for you LostLoach, unless you want a heavily planted tank (with live plants) in which case you might want to go with a substrate specifically designed for planted tanks.
Those would include two of Seachem's substrates, Flourite Black Sand and Onyx Sand. (One small correction to what Crepe wrote, Onyx sand is actually a medium grey color, not black. Flourite Black Sand is the black sandy substrate produced by Seachem. The Onyx is only available in grey AFAIK, unless they've added a second color version of it in recent months.)
