Miracle grow organic potting mix?
How well does it work? Do you ever need to replace it? Do you need to cap it with sand or gravel? Would I need to does any other ferts?

Like any soil mix, for most setups it's best capped otherwise you've got water values all over the place and a serious risk of rampant algae. Eventually after some time, usually a year or two, it will need replacing. Dosing other ferts could be necessary but you can't decide it until you've seen the plants growing or not and you see defficiencies.

Are there any that don't need to be replaced?

Not capping it will result in a muddy tank. You will never have to replace it. But the nutrients in it will eventually be depleted. By the time this happens, you will surely have enough nutrients from the fish waste that will build up in the tank to sustain plants. Root tabs, and dry ferts can also, and actually may needed to be used depending on your lighting, CO2, and plants that you keep.
