Finally, the plant life will make the tank much easier to maintain.
Well, personally I would never introduce any macros,
particularly a Caulerpa sp. into my main display, but that's just me...
Caulerpa is known to emit noxious compounds that can cause problems for other organisms in the system. It can also periodically go "sexual", melting down and making a mess of your system. Further, once their stolons are attached to the rockwork, good luck getting them out of the tank if you decide later you don't want them. Also, a fast growing macro can require constant trimming so that it doesn't irritate or overgrow neighboring corals. Not my idea of low maintenance...

Nothing consumes nutrients or toxins better than live plant life. IMO
Well, there are different philosphies here as well. Some macros can actually
release toxins and/or nutrients into your system. If you're going to use macros for export, I'd recommend keeping them in a separate tank, plumbed to the main system rather than in the display itself. That way, if there's a problem it's easy to isolate this stuff from your main system.
I guess what it boils down to is that some folks choose to deal with waste products after-the-fact with nitrate/phosphate resins, algae scrubbers, sandbeds, etc. Some choose to remove wastes before they become dissolved nutrients through such practices as aggressive protein skimming, strong circulation to keep detritus suspended, activated carbon use, good husbandry practices, etc. Others combine different strategies.
Clearly all of these tactics can work to some degree and what is "best" probably depends more on how you want to run your system and what you're trying to accomplish with it.
JMO of course...
