[font="Arial""]As per title please, I am setting up a 70 litre tank tomorrow with sand. I would like to know roughly how thick/deep I should lay the sand, and how to plant into it. Do I need a base layer of something, or plant right into the sand? I don't have that many plants at the moment as I am upsizing from a 28 litre tank. A picture of my plants is below, and I shall probably add more of the same really:[/font]
