I think your should try to minimize the amount of nutrients in a tank. The bacterial is unimportant. They will reproduce and multiply very quickly.
Many people who used to have a deep sand bed (I am in that group) recommend a remote sand bed (remote from your display tank) so that you can remove and exchange them for nutrient removal with minimal disturbance to the tank.
