## Summary description

sera Bio Nitrivec is a water conditioner designed to establish and maintain a healthy aquarium environment. It contains beneficial bacteria that help to break down harmful substances, ensuring clear water and a balanced ecosystem. Suitable for freshwater and marine aquariums.

## Long description

sera Bio Nitrivec 250 ml is a liquid water conditioner that establishes and supports a biological filtration layer in freshwater and marine aquariums. The product supplies concentrated, live purification bacteria that accelerate the breakdown of toxic nitrogen compounds and reduce cloudiness. Mineral volcanic rock in the formulation binds suspended particles and provides a surface for the biological culture to colonize, helping to stabilise the aquarium environment and maintain clear water.
Advantages
sera Bio Nitrivec introduces high concentrations of beneficial bacteria to speed up the conversion of ammonium and nitrite into less harmful compounds, contributing to a balanced nitrogen cycle. The included mineral volcanic rock absorbs fine particles and provides additional surface area for bacterial settlement, which supports long-term biological activity. The combination of bacteria and mineral carrier reduces water cloudiness and helps produce a biologically active, clearer aquarium environment.
Suitable for
Freshwater aquariums requiring biological establishment or recovery
Marine aquariums that need biological support after setup or maintenance
Tanks after partial water changes or filter cleaning to re-establish bacterial populations
New aquariums during initial cycling to reduce toxic ammonium and nitrite
Key specifications
Form: liquid conditioner with suspended mineral volcanic rock
Volume: 250 ml
Active principle: live purification bacteria for biological nitrification
Application: suitable for freshwater and marine aquaria
Effect: promotes breakdown of food residues, ammonium and nitrite; reduces cloudiness
How to use
Shake the bottle gently before use to distribute the mineral volcanic rock and bacterial culture. Dose according to the instructions on the label based on aquarium volume. Add directly to the aquarium water evenly across the tank. When combined with a general water conditioner such as sera aquatan, fish may be introduced after 24 hours under appropriate acclimatisation. Repeat dosing as recommended after larger water changes or filter maintenance to restore biological activity.
Usage recommendations
For optimal results, maintain stable temperature and aeration during and after application to support bacterial establishment. Avoid overdosing and follow the manufacturer’s dosing table; store the product in a cool, dark place and use within the expiry period stated on the packaging.
