I just removed all the sand in my nano 15 gallons and replaced it by brand new sugar size white sand. I did not have any cycle. I have 2 small clownfish and a small leopard wrasse.
I did not have a lot of sand though in a 15 gallons, so maybe in a larger tank the sand bed play a bigger role in the bio filtration.
