Using sand from the ground a bad idea?
I'm going to be setting up a shell dweller tank soon, and I was going to use silica sand from a building supply store. Cheap, quartz, and, well, quite white. However, my town is Sand City, it is everywhere. It's a nice light brown color, much more natural looking.
This will be a non-planted tank. Could I dig some up, wash it, sift it, bake it, give it the evil eye, and make it safe for the fish?
Thanks much for any input.
Wouldn't you like to beside the seaside?
