The WC's will definitely take care of the elevated nitrates, but they won't address the how they got to be that high.
I may have missed, but what livestock do you have in your tank? I see 3 fish, a cleaner shrimp, GSP, and various snails/crabs from your picture. Really large water changes can impact coral health, so youIl want to keep that in mind since you have GSP. TBH, I don't know how they would react to quick decreases in nitrate and phosphate.
How much do you feed daily? What is your current WC regime? 10-20% weekly is a good level to target for long term maintenance planning as well. I personally try to target 10-15% weekly.
Back to your main question though!
My 75g didn't have a sump or skimmer for the first 2ish years it was up. I used a HOB filter (so I could run carbon and GFO) and then a modified HOB refugium. Eventually I made a DIY sump using an ESHOPPS external overflow box and a 20g tall. While I had to keep an eye to make sure the siphon stays during feedings when I first set it up (I totally turned off my return pump), that upgrade on the tank was probably my favorite as I could move everything out of the display besides my wavemakers.
