## Summary description

Hagen bacterial strains solution, 250 ml (MPN 70627), provides a concentration of beneficial bacteria intended for aquarium biological filtration and faster nitrogen cycle establishment. Designed to seed filters, reduce ammonia and nitrite spikes after setup or maintenance, and support a stable aquatic environment for freshwater tanks.

## Long description

Hagen aquarium bacterial strains solution 250 ml supplies concentrated beneficial bacteria formulated to support biological filtration and speed up the nitrogen cycle in freshwater aquariums. The liquid preparation is intended for use during initial tank setup and after filter or substrate maintenance to help reduce ammonia and nitrite spikes and to promote a more stable water environment for fish and plants.
Advantages
The Hagen solution delivers a ready-to-use blend of nitrifying and heterotrophic bacterial strains intended to colonize mechanical and biological filter media quickly. By introducing established bacterial populations, it can shorten the time required to reach stable levels of ammonia, nitrite and nitrate compared with untreated setups. The liquid format allows even distribution throughout the water column and filter, and the 250 ml volume provides multiple treatments for small to medium tanks depending on dosing instructions.
Suitable for
New freshwater aquarium setups requiring rapid biological cycling
After deep substrate cleaning or filter media replacement to re-seed biological filtration
Systems recovering from elevated ammonia or nitrite where beneficial bacteria are depleted
Planted tanks and community setups that benefit from stable nitrogen processing
When it may not be suitable
This product is intended to assist biological filtration and is not a chemical treatment for removing toxins instantly; it supports the bacteria that process ammonia and nitrite but will not immediately neutralize these compounds. It may be unnecessary in well-established, heavily populated systems with healthy bacterial colonies or in marine/saltwater aquaria where different bacterial strains and treatment approaches are required.
Key specifications
Form: liquid bacterial culture suitable for aquarium dosing
Volume: 250 ml
Intended use: biological filtration support and nitrogen cycle acceleration in freshwater aquaria
Compatibility: suitable for freshwater aquarium systems, filter media, and substrate seeding
How to use
Follow the dosing instructions provided on the product label. Typically, add the recommended volume directly to the aquarium water or pour onto filter media to distribute bacteria where biological filtration occurs. Use during initial aquarium setup, immediately after significant filter maintenance or media replacement, and after water chemistry disturbances to re-establish bacterial populations. Monitor ammonia and nitrite levels with test kits and repeat dosing as advised until stable parameters are achieved.
What to consider before purchase
Intended for freshwater tanks; verify suitability if keeping brackish or marine species
Not a substitute for regular water testing and mechanical filtration maintenance
Store according to label instructions; live bacterial products may have storage temperature requirements
Usage recommendations
Use in combination with regular water testing and gradual stocking. When starting a new aquarium, add the product during setup and after every major filter or substrate change until ammonia and nitrite remain at zero. Avoid overdosing; adhere to the manufacturer's label for dose frequency and amounts.
