Hell R2R fam, im considering running biopellets on my system. Im a heavy gfo advocate simply because it works if you understand how to use it and not let your phosphates bottom out completely. Dont even need to test anymore and i know my phosphates are always in the realm of 0.03 - 0.08 with my heavy feeding. Water changes can not keep up for the nitrates so i see biopellets being my thing. Any advice??
