Tetra FilterActive Bacteria 2-in-1 Mixture for Freshwater Aquariums, 250 ml

Tetra FilterActive Bacteria 2-in-1 Mixture for Freshwater Aquariums

Highly active live bacteria to support permanent biological activity in your aquarium. Accelerates the breakdown of harmful impurities like ammonia and nitrite, optimizing filter cleaning capacity for crystal-clear water.

Contains a blend of live starting bacteria and mulm-degrading cleaning bacteria. Re-balances bacterial losses from water changes or filter cleaning, ensuring immediate biological activity. Nitrificants colonize filter materials to break down toxins, while cleaning bacteria naturally degrade organic pollutants like fish waste and plant residues.

Promotes bio-activity in the substrate, prevents sludge buildup, and enhances fish health. Easy-to-use liquid formula works 100% biologically without clouding water. Ideal for supporting biological activity in heavily stocked aquariums.
