Hey folks, I've been playing around with small DIY reactors for over a year now, and I have installed quite a few in different aquariums. And I thought I'd share the latest design, which you can grab and print if you like at https://www.printables.com/model/292376-aquarium-reactor
There's also a lot of information about it there as well.
Cost of materials isn't too bad:
Acrylic Tube: 4" x 3" OD 2 3/4" ID : $6
Pump at Amazon: $11
3D plastic: ~$4
Laser cut Acrylic pieces: ~$4
So, it's under $30 all-in if you have a 3D printer and a Laser cutter.
