It all depends on the type of tank. I really like the look of sand so we often use either pool filter sand or blasting sand depending on the color we are going with. That said we tend to use florite in our planted tanks. But of course now that we are looking at getting our fish room going again I think I will go with the bare bottom there and only use substrate in our show tanks in the front of the house.
