40 times volume flow?

That's a lot of flow for the corals on your list. 20x would be better IMO. It doesn't have to be continuous direct flow either, alternating and faster/slower speed rates are more natural. Getting the flow to cover all the nooks and crannies of the tank is more important than actual flow rates. It helps keep algae and cyno at bay and is good for nutrient export to feed the corals and keep things in suspension for waste removal.
