Bioscape Carbon & Phosphate Cartridges Velocity 400/700 2Pk
One cartridge, two filters – the carbon and phosphate refill for the Bioscape Velocity 400 and 700. Bioscape shares a single cartridge across its two smallest internal filters, so this two-pack refits either a Velocity 400 (400 L/h, up to 40 L) or a Velocity 700 (700 L/h, up to 70 L).
Key features
- Fits two filters, not one – the same cartridge services both the Velocity 400 and Velocity 700.
- Two cartridges per pack – keep a spare ready rather than waiting on a reorder.
- Removes tannins, chlorine and phosphate – activated carbon lifts discolouration and odour; the phosphate pad strips the phosphate that drives algae.
- Freshwater and marine safe – nothing in the media affects invertebrates or plants.

Care and maintenance
No fixed interval is published by Bioscape. Check the cartridge monthly and swap it once it stops clearing colour or odour from the water. Rinse a new cartridge before fitting to clear loose carbon dust.
Warranty and delivery
Covered by your consumer guarantee rights under Australian Consumer Law if faulty on arrival. Ships as a small parcel.
Common questions
Does one pack service both my 400 and 700 filters?
Yes for spares – the cartridge itself is identical – but each filter needs its own cartridge fitted, so a single 2-pack covers one swap on each of a 400 and a 700, not both filters running long-term from one pack.
Will this fit my Velocity 1000 or 2000?
No. Both use their own model-specific cartridge (2000 = BIS174).
Is it reef safe?
Yes, the media carries nothing that affects marine invertebrates or corals.
