Bright white wont be bright white for long.. Stick with any type of aragonite. Silica is very controversial (even though I use it in my sump). At the very least, aragonite doesnt scratch your glass as easy as silica if it gets caught in your magnet.

it does say "aragonite" sand tho.

I'm fond of OceanDirect Original Grade and Oolite. It's usually sold as a livesand.
