Bioscape Tropic Replacement Pump for Clearview Desktop Aquarium
Restore full flow to your Clearview Desktop Aquarium's built-in filter. This is the replacement pump for the Bioscape Tropic Clearview Desktop Aquarium 20 L (model AC18) – the part that drives the unit's built-in multi-stage power filter. Fit it when the original pump has weakened, seized or stopped, to bring the filter back to its designed circulation through the tank's mechanical and biological media.
Key features
- Genuine fit – engineered specifically for the Clearview Desktop Aquarium 20 L (AC18), not a universal part.
- Like-for-like replacement – swaps in for the original pump without needing a different filter housing or media basket.
- Restores designed flow – brings the built-in filter back to the circulation it was designed to run at.

Compatibility
Fits the Bioscape Tropic Clearview Desktop Aquarium 20 L (AC18) only. It is not a fit for other Bioscape tank units, including the Tropic Hydro Half Moon or any of the Bioscape PRO range – check your tank's model before ordering.
Care and maintenance
If flow still feels weak after fitting this pump, check the filter cartridge and media first – a clogged cartridge is a more common cause of poor flow than a failed pump, and replacing the pump won't fix a media problem.
Warranty and delivery
Covered against manufacturing defects under Bioscape's warranty, in addition to your rights under Australian Consumer Law.
Common questions
What does this pump fit?
Only the Bioscape Tropic Clearview Desktop Aquarium 20 L, model AC18. It isn't a universal part.
How do I know my pump has failed?
Signs include reduced flow from the filter outlet, unusual noise, or the impeller not spinning. Check the filter cartridge and media aren't clogged first, since that's a more common cause of weak flow.
Does Bioscape publish this pump's wattage or flow rate?
Not anywhere we could verify. Contact us if you need that figure confirmed before you order.
Where do I find fitting instructions?
Bioscape publishes a manual for the Clearview Desktop Aquarium (AC18) on their manuals page – check there, or ask us, before you start.
