Air powered, modular, semi underground aquarium filter

thingiverse

under gravel aquarium filter, modular and repeatable. I printed this up when my filter kept getting clogged. I have made it modular; the bottom parts go under the gravel. You can add another air tube for more suction if you repeat the under filter sections. Seems to be working really well. Add some filter material in the middle tube, so you can easily see if it needs a clean. You will need to shave off the chimney edge to insert it. I found this was a reliable way to get a tight fit. Use the separate air hose thingy file; The ones in the other file break.
