Aquarium biological filter using filament purge media
About
I've always thought PETG filament purge waste will make great bio-media for aquarium filters.
This model is an air pump driven filter that can be printed without supports and consists of only 2 parts. It is ideal for quarantine or smaller tanks.
Printing
Use PETG for both the filter and the bio-media.
Use good quality PETG to get a good print.
No supports are required.
Assembly and Use
Add a layer of rock gravel to the bottom of the filter, to weigh the filter down when underwater.
Pack the filter full with PETG filament purge waste.
Cap with the lid.
Connect the filter using standard 3/16" / 4mm air tubing to an air pump.
Note: After placing the filter underwater, please tilt the filter slightly to allow trapped air under the cap to escape.
Tip: Run a blowtorch over the filament purge waste before use, to get rid of any fine strings.
