Nitrates between 10 and 20 ppm, not going down, getting mixed advice

If you have a chance, please take a snapshot inside/of your overflow/filter setup. We may have some suggestions for improvement, maintenance, etc.

I'll give it a try after work in about 3 hours.

I mean I get that but you could just not export as much, not essentially waste import by doing so and still give good advice to new people that this kind of approach isn't realistic for. It's definitely not the ideal solution for newcomers who have no sense of this balance.

It isn't wasting "import" as the corals, fish, and microfauna are all using it. The export in my tank is all of my cnidarians and then my refugium for waste products.
