## Summary description

Sera 8400 is a water conditioner designed for aquariums, effectively clarifying water. This 250 ml product from Germany helps maintain clear and healthy water conditions for fish and aquatic plants.

## Long description

Sera 8400 aquarium water clarifier is a 250 ml water conditioner formulated to improve water clarity in freshwater and planted aquariums. Produced in Germany by sera, this clarifier works to aggregate microscopic particles and organic residues so they can be removed by filtration or settled out, helping to maintain clear, healthy-looking water for fish and aquatic plants.
Advantages
This water clarifier targets suspended particles and colloidal matter to reduce cloudiness without altering water chemistry. The formulation is designed for compatibility with typical aquarium environments and aims to support existing biological filtration. Packaged in a 250 ml bottle, it offers a measured, easy-to-dose solution for routine water maintenance and for restoring visual clarity after disturbances.
Suitable for
Freshwater aquariums with fish and live plants
Clarifying cloudy water after substrate disturbance or plant trimming
Use after water changes to speed up clearing of suspended particles
Short-term use following minor contamination or overfeeding
Key specifications
Volume: 250 ml
Intended use: aquarium water clarification
Compatibility: formulated for freshwater aquariums
Effect: aggregates suspended particles for easier removal by filtration or settling
Origin: manufactured in Germany
How to use
Dosage instructions should be followed as indicated on the product label. Add the recommended amount directly to the aquarium water, distributing it evenly across the surface. Run mechanical filtration and, if available, increased gentle circulation to help carry aggregated particles to the filter. Observe fish and invertebrates for any behavioral changes and repeat treatment only if recommended on the label. Avoid overdosing and do not mix simultaneously with incompatible chemical treatments unless the label permits.
Usage recommendations
Use the clarifier as a targeted treatment for water cloudiness; combine with regular mechanical filtration and routine maintenance such as partial water changes and substrate vacuuming for best results. Store the bottle closed and out of reach of children, and refer to the label for specific safety and dosage guidance.
