Do reactors equal less water changes?

[GoFish]

Just thinking of automating the setup a little more.
I do a 10-20% water change every 7-10 days. Currently no problems with algae but as time goes in the hobby the ole powerhead/heater in a bucket in the bathroom overnight routine is feeling a little monotonous.

Do people generally use reactors to allow less frequent water changes?
Or for other reasons?

Second option is to keep the same setup now and look into an auto water change system...
