FS: GEO420 Reactor


New member
Bottom up feed design. Great for GFO, Carbon or bio pellets. I used it for a while as an added conditioning tool filling it with bio-balls. The up-flow design prevented the bio balls from collecting detritus and becoming nitrate factories as they are known for. I added adapters so the input and output are johnny quest fittings for 1/2" tubing. I have tons of of fittings to provide you with what you need to plumb this into your tank. They are also removable if you want to use hard plumbing instead. The reactor is in great condition and no leaks. Asking $40 OBO.
