Hanna HI782 in freshwater

[Malcontent]

Diluted with 5 mL RO/DI so it's giving me 148.8 mg/L!

Not diluted but it's in NO3-N which converts to 99.6 mg/L nitrate! I did a ~95% water change on 10/30 so this is pretty surprising. And my 2nd largest fish is in fish jail for being aggressive while my 3rd largest is in the FICU (fish ICU). If one or both of them return the bio load is going to increase substantially.

My tap water. Also, not cranberry juice.

Going to test both tests against fresh and saltwater nitrate standards in the coming months.

This is a marine (saltwater) system, yes?
