Breeding Tank Sponge Filter

thingiverse

This simple sponge filter works great for breeding and baby tanks. It uses two zip ties, an airline, an air pump, and a porous sponge from your local fish store. To assemble, print the template, attach the airline, wrap the standpipe with the sponge and zip ties, then add the air pump. Easy! For more info on sponge filters, check out this URL: http://www.jehmco.com/html/hydro-sponge_filters.html. The scad file is attached if you want to make changes, and assembly photos are included. Enjoy your new filter! If your LFS has pre-made sponges, you're in luck. Otherwise, create a 20mm hole in a flat sponge or zip tie a sponge around the standpipe. Feel free to share any improvements to this design.
