To add a biopellet reactor or not??

I believe adding biopellets will reduce your nitrates, but you might experience a rise in phosphates. Remember the Redfield ratio is 106:16:1. You mess with one and another of the three might become the limiting factor. Adding biopellets (C source) will help you lower N for sure. But you will still need phosban to lower phosphates.

I run both biopellets and ROWAphos and I'm happy with my tank. Just start small, and increase the amount of biopellets gradually.
