## Long description

HAPPET FILTR DELFIN 200 is an internal aquarium filter designed for mechanical and biological filtration in freshwater tanks. The unit mounts inside the aquarium and provides continuous water circulation through layered filter media to remove debris and support beneficial bacteria. Its compact design is intended for small to medium aquaria where unobtrusive, reliable filtration and improved water clarity are required for routine maintenance.
Advantages
The internal placement of the filter reduces external plumbing and saves space around the aquarium. Layered filtration media capture suspended particles and provide a stable surface for nitrifying bacteria, supporting biological balance. The DELFIN 200 operates continuously to maintain steady circulation and oxygenation, and its simple construction allows easy access for cleaning and media replacement without specialized tools.
Suitable for
 Small to medium freshwater aquariums
 Community tanks with low to moderate stocking levels
 Breeding setups that require gentle water flow
 Quarantine or hospital tanks for routine maintenance
Key specifications
 Internal installation for in-tank use

 Accessible media compartment for cleaning and replacement
How to use
Install the HAPPET FILTR DELFIN 200 inside a clean freshwater aquarium following the manufacturer’s mounting instructions, ensuring the unit is fully submerged and placed to promote even water flow. Load the supplied or compatible filter media into the compartment, connect to power with the aquarium cover in place if required, and check for steady circulation. Inspect the intake and media periodically and perform routine cleaning by rinsing mechanical media in aquarium water and replacing or renewing biological media as needed to maintain filtration efficiency.
Usage recommendations
For optimal performance, match filter capacity to the aquarium volume and stocking level, avoid overfeeding to reduce load on the media, and schedule regular maintenance checks. When cleaning, use water from the aquarium to preserve beneficial bacteria and replace media according to observed water quality and manufacturer guidance.
