ZOA Bacter is a concentrate of non-pathogenic live bacteria fixed on a maerl substrate, designed to stabilize the biological balance in both saltwater and freshwater aquariums. Its multi-strain consortium naturally competes with unwanted algae, lowers nitrates and phosphates through assimilation, and transforms organic deposits into resources for filtration. Result: cleaner windows, clear water and a healthier biotope. Fish and corals regain vitality and resistance (protection against vibrioses), while a beneficial biofilm is established to feed certain invertebrates. Compatible with skimmers and filters, the effect is quickly seen, especially with correct mixing. 40 ml bottle (34 g) – 10 9 CFU/g , GMO-free, no risk of overdose .
Mix the Zoa Carbo in a quantity of reverse osmosis water according to the volume and the desired concentration. This table will allow you to prepare 5 liters of solution in single, double or triple concentration. These doses are to be dissolved in reverse osmosis water. You can prepare smaller or larger quantities by dividing or multiplying the doses below.
