Do reactors equal less water changes?

So as I understand it at this point, my answer is no.

I think the question means:

If I am controlling nutrients already, such as a skimmer for nitrates, and GFO for phosphates, does a reactor contribute enough trace elements to extend the period between water changes.

I've often wondered this myself. If my nitrates are at 0, and my phosphate are .01 or .02 ... what am I doing a water change for?

I've heard of people adding magnesium crystals their calcium reactor media as well to help keep mag in check while running a reactor.
