Bioscape Tropic Easy Clean Hang-On Filter

Bioscape rates the 160 L/h model for 16 to 38 litre aquariums, the 320 L/h model for 38 to 75 litre aquariums, and the 450 L/h model for 72 to 110 litre aquariums. If your tank is right at the edge of what a mid-size hang-on filter should handle, get in touch and we'll help you match the model to your setup rather than guess.

• Three-stage media – fine wool, activated carbon and bio-balls, all included in the cartridge.
• Modular cartridge system – the whole media stack pulls out as one unit for a fast clean, rather than fishing out loose media by hand.
• Sponge pre-filter – a sponge cover on the intake catches coarse debris before it reaches the main media, extending cartridge life.
• Quiet hang-on operation – sits on the tank rim with no plumbing to run.
• Three sizes, one design – 160, 320 or 450 L/h, so you can match flow to tank size instead of over- or under-filtering.

Each unit ships with the filter body, an intake strainer with sponge pre-filter cover, and a full modular cartridge loaded with fine wool, activated carbon and bio-balls.

Suitable for freshwater community tanks sized to the model's flow rating, as a primary filter on a small tank or supplementary filtration on a larger one. Not intended as the sole filtration on a heavily stocked or heavily fed tank at the top of its size range – pair with a second filter if you're pushing the stocking limit.

Rinse the sponge pre-filter regularly in tank water to keep flow up between full cartridge changes. Bioscape hasn't published a fixed cartridge replacement interval for this model; as a general guide, carbon exhausts chemically well before it looks dirty, so replace that stage every few weeks and rinse or replace the wool and bio-ball stages as they visibly clog.

What's the difference between the three sizes?

Flow rate and power scale together – 160 L/h at 3 W, 320 L/h at 5 W, and 450 L/h at 7 W – so you can pick the size that matches your tank rather than one filter doing every job.

What tank size does the 160 L/h suit?

Bioscape rates it for 16–38 L aquariums.

Does the cartridge need to be replaced as a whole unit?

The modular design lets the whole cartridge pull out for cleaning or replacement in one piece, rather than separating the media stages by hand.

Can I run this alongside a canister or sump?

Yes – it works well as supplementary filtration or as backup mechanical and carbon filtration on a tank that already has a primary filter.
