Bioscape Black Foam Insert Motor Compartment 1000 4Pk
Genuine replacement foam for the motor compartment of the Bioscape Velocity 1000 internal filter. This four-pack fits inside the motor housing around the impeller, keeping debris out of the impeller shaft while the main mechanical, carbon and phosphate media do the bulk of the filtering.
Key features
- Fits the Velocity 1000 internal filter — sized for the motor compartment / impeller housing, not the main intake foam.
- Four-pack — enough for several servicing cycles without reordering each time.
- Protects the impeller — stops fine debris reaching the impeller shaft, which is what causes humming or reduced flow as a filter ages.

Which foam insert do I need?
Bioscape's Velocity range has a matching motor compartment insert for each filter size — this one is sized for the 1000 model only. The 1500 and 2000 filters use their own equivalent inserts (BIS178 and BIS179); check your filter's rating before ordering, since the housings aren't interchangeable across sizes.
Care and maintenance
Rinse the old foam in tank water during routine filter cleaning and reuse it while it still holds its shape. Replace it once it's compressed, torn, or no longer sits snugly in the motor housing — a loose-fitting insert lets debris past it and onto the impeller.
Warranty and delivery
Sold as a standard consumable replacement part; any fault on arrival is covered under your consumer guarantee rights under Australian Consumer Law. Ships as a small parcel.
Common questions
Is this the same as the main filter foam?
No. This insert sits in the motor compartment around the impeller. The primary mechanical foam that does most of the filtering is a separate, larger part.
Will this fit my Velocity 1500 or 2000 filter?
No — it's sized for the 1000 only. The 1500 and 2000 use their own motor compartment inserts (BIS178 and BIS179).
How often should I replace it?
As soon as it's compressed, torn or no longer fits snugly — typically every few months with regular filter cleaning, though this varies with bioload and how often the filter is serviced.
