This external bucket prefilter is for hobbyists who want to reduce how often the main filter needs cleaning. It catches debris at the intake, so the main filter media stays cleaner for longer.
Why it matters
- Three sponges of different grades plus bioballs trap dirt, sediment and organic residue before the water reaches the main filter.
- Transparent body lets you check how dirty the prefilter is without opening it.
- Detachable valves allow the unit to be removed for cleaning without draining the aquarium.
- Locking lid with a rubber seal closes on clips, which keeps the unit sealed during operation.
