For your consideration, get a midsize tank 40 - 70 gal with a sump, Use an algae scrubber in combination with a sulfur denitrator.
This is essentially my setup. I have a 50 gal tank, with a sump, an algae scrubber and a DIY sulfur denitrator fed by my overflow. Every two weeks I clean the scrubber for about 10 - 20 minutes.
I rarely do water changes and my nitrate is 0, even with feeding four times a day with an automatic feeder. I top off water every few days by hand. And every week I dose CA, MAG, and other stuff by hands.
You can always get an ATO and doser to cut back on work.
