How can there be sand in a freshwater aquarium?

I see pictures and videos that show tanks with Bettas and sand instead of gravel or pebbles. I always thought that if you put sand in a freshwater tank it would become salty. Also, how do people have sand with no Algae growing on it? I have a saltwater tank and the sand is all green and brown from algae. Thanks for the help!
