ZOA Bacter – 40 ml | Concentrated anti-algae bacteria & crystal clear water

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 .

• Visible reduction in filamentous algae and less dirty windows.
• Progressive reduction of nitrates and phosphates, clear and stable water.
• More toned corals and fish, reinforced and sustainable microbial flora.
