Overview
Aquarists with mid size tanks get a hang on filter that pushes water through a large basket of foam, carbon and ceramic media. Hang it on the rim, prime it, and swap each media type on its own schedule.
A deep basket gives long media contact and lets you replace foam, carbon and ceramics separately, which saves buying cartridges. It hangs on the tank and needs frequent rinsing to hold flow.
Who it's for
Beginners and experienced aquarists with common tank sizes will manage it easily. Large or heavily stocked tanks may need a bigger model.
Pros and cons
- Large media basket
- All media types included
- Separate media replacement
- Fresh or saltwater
- Hangs on tank rim
- Regular cleaning needed
- Flow rate not listed
Performance notes
Contact time is the key, since water passes through a deep stack of media rather than a thin pad. Chemical filtration from the carbon fades and needs replacing. Biological media gains strength as bacteria settle in.
