Reduce Nitrate need opinion.

[Coleus]

+1 for biopellets, I have been fighting the nitrate problem until i use biopellets. I tried so many different way such as regular water change, reduce feeding, nitrate reducer chemical, etc .... but nothing works wonder like biopellets. I went from 40ppm to nearly zero now (if my test kit is correct). However, i notice my lps also suffer, they seem to grow slowly. I have to increase feeding now
