If you use a scrubber aeration box, or a vertical substrate sheet, algae scrubbers work well, but it's much more efficient to use plants in the fuges than micro algae.
Plants like emergent water sprite, peace lilies, moss, etc work great
But it's not about export of nutrients for most planted tanks with CO2, it's much more about plant dominance and stability. We add nutrients, not really want to export, so the goals are very different for the diaplay and the fuge, this is also true for marine systems.
You can have a planted marine tank where you have to dose and add ferts.
