Description

The Fluval AC High Performance Filters are hang-on-back external filters for freshwater and marine aquariums. They feature a well-engineered design with an especially efficient filtration concept. Unlike conventional hang-on filters, they incorporate a patented re-filtration system, which circulates water multiple times through the filter media. This increases contact time with the media, resulting in improved cleaning performance and more stable water parameters. The four-stage filtration consists of an intake sponge, a mechanical pre-filter made of Bio-Foam, a chemical stage with activated carbon, and a biological stage using BIOMAX ceramic rings. All essential filter media are included and can be replaced individually without disturbing the aquarium's biological cycle (CycleGuard principle).

The newly designed media basket provides fast access to all filter inserts and ensures efficient water flow through the structured layout. The revised impeller unit enables smoother operation and significantly reduces noise. An adjustable flow control allows the filter output to be adapted to aquarium needs. After a power outage, Fluval AC filters restart automatically, provided the aquarium water level is above the intake pipe. Thanks to a preformed mounting bracket and compact construction, installation is simple—even on narrow tank rims. The materials used are durable and long-lasting. Fluval AC Filters are an evolution of the established AquaClear series, offering significantly improved filtration performance, ease of maintenance, and media efficiency for consistently clear and stable aquarium water. They are suitable for both freshwater and marine tanks.

Absolutely EXCELLENT - at least after setup

Long-term experience is still missing, but for now full marks! Because, first, not just one sponge but several media in such a small filter! (read more)

Absolut TOP - zumindest nach Inbetriebnahme

Langzeitwefahrung fehlt noch, aber jetzt erstmal volle Punktzahl!

Weil erstens nicht nur ein Schwamm, sondern mehrere Medien bei einem so kleinen Filter! Das sticht schon mal positiv heraus und hat mich auch zum Kauf bewogen… (für ein 45P)

Inbetriebnahme auch easy, lief sofort los!

Und jetzt das Beste: Echt total leise!! ? Das minimale Brummen des Filters ist neben dem Wassergeräusch nur zu hören, wenn man sich direkt neben das Aquarium stellt…

Ich bin erstmal mega zufrieden!

Good filter - quite high-maintenance

I've had the filter in use for a good 3 months on our 70 liter aquarium (Juwel Primo 70) and find it visually appealing and absolutely quiet - the aquarium is in the bedroom. (read more)

Guter Filter - recht pflegeintensiv

Ich habe den Filter seit gut 3 Monaten an unserem 70 Liter Aquarium (Juwel Primo 70) im Einsatz und finde ihn optisch ansprechend und absolut leise - das Aquarium steht im Schlafzimmer. Das Wasser ist klar und er macht seinen Job sehr gut. Sicher bei einem 70 l Aquarium an der oberen Leistungsgrenze, Fluval gibt ein Volumen von 18–76 l an. Ich wollte aber keinen größeren Filter, da die LED-Lampe ja halbwegs mittig auf dem Aquarium sitzen soll.

Bei dem Besatz mit Guppys und Neocaridina Garnelen muss ich den Vorfilterschwamm mindestens einmal in der Woche reinigen, da der Wasserdurchlauf recht schnell nachlässt und der Bio-Foam Filterschwamm ist spätestens alle 3 Wochen dran. Wer sich auf den Pflegeaufwand einlässt, erhält einen sehr guten und vor allem sehr leisen Filter für kleine Aquarien.

Ich würde ihn wieder kaufen!
