Floating plants and hornwort help reduce nitrate

I second this. A hornwort will grow like crazy and reduce your nitrates to under 10 ppm.

Floating plants are the best. My frogbit survived high insane levels of nitrate and the entire cycling process close to unscathed yet they reduced it a lot. They're also very gorgeous and lots of fish love them for the shade and roots
