You will need power heads, for water movement, and to help export nutrients. The water movement helps suspend any detritus in the water, allowing it to be taken up by your filter, as opposed to just settling onto your substrate. Most fish also need some movement.
Although a sump would be a better situation, you could get by with just a large power filter.
Depending on your stocking level, you may also want a HOB
protein skimmer too. With heavy stocking, a skimmer would help to keep nitrates from accumulating. Water changes will bring your nitrates down, but a skimmer will help keep them down.
Hope this helps with your build, and have fun!
