Fluval FX Gravel Cleaner Kit Vacuum Bag Fine 2 Pack
The debris bag for your FX gravel vacuum, replaced. Fluval part A372 is the fine mesh vacuum bag for the Fluval FX Gravel Cleaner Kit, sold as a 2 pack. Fit it to the kit's tube extension before your next water change to catch waste lifted from the substrate instead of letting it recirculate through the tank.
Key features
- Fine mesh weave — traps general debris and waste while still letting water pass through freely.
- Direct fit to the FX Gravel Cleaner Kit — no adapters or trimming needed.
- Sold as a 2 pack — a spare on hand for the next clean once the first bag is due for a wash.
- Reusable — rinse clean and refit rather than replacing after every use.
Will it fit my kit?
A372 fits the Fluval FX Gravel Cleaner Kit (A370) only, which itself connects to the FX4 and FX6 (2nd generation) canister filters. It does not fit any other brand's gravel vacuum.

Care and maintenance
Rinse the bag under a tap immediately after use so waste doesn't dry into the mesh. Let it air dry fully before storing to stop odour building up between water changes.
Suitable for, and not suitable for
Suitable as a replacement or spare bag for any Fluval FX Gravel Cleaner Kit owner. Not suitable for finer sand substrates where debris is small enough to pass through a standard fine mesh — use the super fine bag (A373) instead.

Covered by Fluval's standard warranty against manufacturing defects, in addition to your rights under Australian Consumer Law. Ships as a standard parcel.

Common questions
Does this fit any gravel vacuum, or only the Fluval one?
Only the Fluval FX Gravel Cleaner Kit (A370). It isn't designed to fit other brands' siphons.
What's the difference between this and the super fine bag?
This fine bag suits general debris and waste. The super fine version (A373) has a tighter weave for catching finer sand and light detritus that a fine mesh would let through.
Can I reuse the bag, or is it single-use?
It's reusable — rinse it out after each water change and let it dry before the next use.
