I’m planning out an upgrade from a 75 gallon to a 135 gallon DT, and was given a small sump to add to my existing sump/system that is only designed for a 125 gallon DT, so I’m going to add the small sump and planning a algae reactor to help, does it make sense to have both? A fuge and the reactor? I think there is more benefits to a fuge than just nutrient control.... but from what I’m reading a reactor is just that nutrient control devise... opinions??

Depends on bio load.
Agreed, refugium offers more than just nutrient control. An ats or reactor can reduce more nutrients in less space.
I started my tank with both and took ats off line about 9 months in. Many keep the ats and find there refuge macro fades away and keep it that way.

I started with a fuge early on when I started my 125. I had this great idea that I would add an ATS and eventually convert the fuge into a frag tank of sorts. Well, as my fish grew (especially the tangs), and the bioload grew with them, I found that my heavy in/heavy out approach to nutrient control worked well keeping both going. My fish and corals are really diggin it. I've found that the fuge is a good pod farm (at least mine is), and the ATS (or reactor) is simply a very effective method of nutrient control. It really depends on your bioload and your approach to feeding your fish and corals.
