What is the best form of substrate for a home aquarium? - best home aquariums

I bought a 20 gallon tank and was wondering what most people prefer the substrate.

I thought, between the gravel and sand, and I'm similar to the sand as if it was realistic to fish with sand. But it would be much harder to get through a grit chamber and welcomed me as if I change a water every week to do?
