Thank you Titus. As far as I know BioPellets is removing NO3 and not PO4. GFO removes PO4. I am running refugium and BioBellets for short time, as I was witing for Pellets to kick off. These 2 are overlaping - agree, but I plan to remove Refugium from my system and have just Pellets and GFO with Carbon, Pellets are skimmed. Kein can chime on this as he is more professional.
