Bioscape Replacement Pump Nano 61ltr
Restores flow to a Tropic Nano 61L that's gone quiet. This is the replacement circulation pump for the Bioscape Tropic Nano 61L Aquarium (BIS136) – the internal pump that drives water through the unit's 3-stage filter and back into the tank. It's sized for the 61L unit only and isn't interchangeable with the 24L or 40L Nano units in the same range.
Key features
- Direct-fit for the 61L unit – matches the impeller well and mounting point in the Tropic Nano 61L Aquarium (BIS136); it isn't sized for the 24L or 40L versions.
- Restores full circulation and filtration flow – brings a Nano 61L that's slowed down or stopped back to normal water movement through the filter media.
- Swap-in replacement – lifts out of the impeller well and reinstalls without dismantling the rest of the filter compartment.
- Genuine Bioscape part – the manufacturer's own replacement, not a generic aftermarket substitute.

Suitable for, and not suitable for
Suitable for a Bioscape Tropic Nano 61L Aquarium that has lost circulation or filtration flow, or where the original pump has become noisy despite a clean impeller well. Not suitable for the Tropic Nano 24L or 40L units, and not designed as a fit for other manufacturers' nano aquarium kits.
What's included
The pump ships as a single unit ready to drop into the impeller well. It does not include filter media – Bioscape's polywool filter pads for the 61L unit are sold separately, as is the LED light unit (BIS146), if either also needs replacing.
Care and maintenance
Before ordering a replacement, pull the impeller and clean the well – a slow or silent pump is very often biofilm build-up rather than a failed motor, and a clean and reseat can restore flow without a new part. If flow stays weak or the pump stays silent after cleaning, this is the direct-fit replacement.
Warranty and delivery
Covered against manufacturing defects under Bioscape's warranty, in addition to your rights under Australian Consumer Law. Ships by standard parcel post.
Common questions
How do I know if I need this or just a clean?
Pull the impeller and rinse the well first. If the pump was jammed with biofilm, a clean is often enough. If it's still weak or silent afterwards, this pump is the replacement.
Will this fit my 24L or 40L Nano unit?
No – each Nano size uses its own pump. Use the comparison table above to match the pump to your aquarium unit.
Does it come with filter media?
No. This is the pump only; filter media and the LED light unit are separate spare parts.
Is it a genuine Bioscape part?
Yes – it's the manufacturer's own replacement pump for this unit, not a generic aftermarket part.
