Go for it. I used leveling sand from home depot in my tank and its perfectly fine. Just rinse it off really well first. here's a pic of two of my gars chillin out on the bottom of the tank with the leveling sand.

I have used granite pea gravel in tanks and it is just fine. Have a look at the gravel and if it is granite use it without worry.
