ZOA Bacter is a concentrated blend of non-pathogenic live bacteria attached to 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 nitrate and phosphate levels through assimilation, and transforms organic deposits into resources for filtration. The result: cleaner glass, clearer water , and a healthier ecosystem. Fish and corals regain vitality and resistance (protection against vibriosis), while a beneficial biofilm develops to nourish certain invertebrates. Compatible with protein skimmers and filters, the effect is quickly noticeable, especially with adequate water flow. 1000 ml bucket (850 g) – 10⁹ CFU/g , GMO-free, no risk of overdose .

At the heart of ZOA Bacter is a synergistic blend of beneficial strains deposited on a highly porous maerl substrate. These microorganisms rapidly colonize the aquarium decor, compete with algae for nutrients , and transform organic sludge into usable compounds. Simultaneously, they capture nitrates and phosphates to multiply: fewer nutrients mean less algae and clearer water. The resulting biofilm stabilizes the aquarium and nourishes certain benthic species, while keeping the glass cleaner for longer.
By restoring a robust bacterial flora , ZOA Bacter supports the overall immunity of the aquarium and limits the establishment of opportunistic bacteria such as Vibrio. LPS and SPS corals particularly appreciate this stability: easier acclimation, tissues less prone to necrosis , and more open polyps. Fish often exhibit more active behavior and improved appetite.
For an effective start, perform a 2-week seeding (measuring spoon included). During distribution, turn off the skimmer or rapid mechanical filtration for approximately 10 minutes and pour the dose into a well-circulated area.
Next, switch to a weekly maintenance dosage : 2.5 ml (≈ 1 spoon) for 500–1000 L, and 1.25 ml (≈ ½ spoon) for 30–500 L. The absence of overdosing makes use worry-free: adjust according to the organic load and the response of the tank.
ZOA Bacter perfectly complements a high-performance protein skimmer, mechanical filters, and biological filters . In reef aquariums, the effect is often spectacular under strong water flow . In freshwater, the reduction in nutrients makes the aquarium more stable, with a less clogged substrate . Also suitable for use in outdoor ponds at temperatures above 15°C .
