Questions about Bio-pellets

[Myka]

I see no reason to use biopellets if there is no issue with elevated NO3 or PO4. I swear by biopellets in situations where a tank needs to be cleaned up, but once a tank is cleaned up, biopellets aren't necessary or even particularly useful IMO. Biopellets can be very aggressive.

If you like the idea of a bacteria and carbon source system, check out Prodibio BioDigest and BiOptim. You only dose them once every 15 days (just pour it in the sump), and it is not aggressive like biopellets. Anecdotally, it seems to help keep the good bacteria population up which helps to keep bad bacteria populations down. I've been using it for a few years now.
