A large hang on filter with adjustable flow and a media basket that blocks bypass, a good fit for larger freshwater tanks. It still hangs on the rim and needs regular cleaning.

Overview
Not a cartridge filter, the AquaClear power filter uses a deep basket of foam, carbon and ceramic media that water must pass through. A flow control lets you slow the current for gentle fish, and the waterfall return adds oxygen.
Owners of larger tanks get adjustable flow and no bypass around the media. The filter hangs on the back, and the media needs rinsing every couple of weeks.
Who it's for
Keepers of larger community or planted tanks will use the flow control. Very heavily stocked tanks may still need a canister.
Pros and cons
- No media bypass
- Waterfall return oxygenates
- Large media volume
- Hangs on tank rim
- Cycle Guard not listed in box
- Regular cleaning needed
Performance notes
Filtration efficiency comes from the basket design, which stops water slipping around the media. Flow control lets you match current to fish, and lower flow also raises contact time. The waterfall return breaks the surface for gas exchange.
