## Long description

sera Nitrite minus, 500 ml, is an aquarium water treatment solution formulated to reduce dissolved nitrite in freshwater tanks. The product is intended for use when nitrite concentrations are elevated or as part of routine maintenance to maintain safer water conditions for fish and invertebrates. The liquid concentrate is dosed into aquarium water to bind or neutralize nitrite, helping to lower acute nitrite levels and decrease the risk of nitrite-related stress or poisoning.
Advantages
sera Nitrite minus provides a targeted approach to lower nitrite concentrations without requiring immediate water changes. The 500 ml bottle supplies multiple doses for recurring treatments in small to medium aquaria. The formulation is designed for compatibility with common freshwater setups and can be used alongside standard water conditioners and biological filtration. Usage follows clear dosing instructions printed on the label to ensure controlled application.
Suitable for
 Emergency reduction of raised nitrite levels in freshwater aquaria
 Routine maintenance when nitrite spikes are likely (after new setups or livestock additions)
 Aquariums with sensitive fish or invertebrates prone to nitrite stress
 Temporary treatment during filtration disturbances or cycling
Key specifications
 Product form: Liquid concentrate
 Volume: 500 ml
 Intended use: Reduction of dissolved nitrite in freshwater aquaria
 Compatibility: Designed for freshwater fish and invertebrate environments
 Application: Dosed directly into aquarium water according to label instructions
How to use
Follow the dosing instructions printed on the product label for accurate application. Measure the aquarium volume and add the recommended dose of sera Nitrite minus directly to the tank water, distributing it evenly. Monitor nitrite levels with a test kit after treatment and repeat dosing only as specified on the label if elevated nitrite persists. Continue regular maintenance such as partial water changes and ensure biological filtration is functioning to address underlying causes of nitrite accumulation.
