from what my understanding, dosing of polylab products you don't need biopallet. bio pallet is slowly release of organic food from these plastics promotes the development of bacteria that assimilate nitrate and phosphate. These bacteria can be harvested by protein skimmers, so that the nitrate and phosphate levels are naturally reduced. The bacteria are also a food source for filter-feeding invertebrates such as corals, clams, sponges, and feather dusters. and poly lab products are food source of bacteria and concentrated acid. seniors who's using it too pls correct me if im wrong. currently im using it with rowaphos and to be honest before i use this product my corals are so called unhealthy. after dosing this for weeks i see colours are improving up.
