Most planted tank folks don’t use a sump. I have a sump for my rack of 10g tanks but they’re not planted tanks. The sump is a point where you degass your valuable co2.
I drill holes on the side of my tanks. You can get cheap bulkheads on amazon or eBay. Get the right glass hole saw bit too and practice drilling on scrap glass first.
