$30 DIY Media Reactor

diy-reactor

For a couple hours and $30 you can build your self a custom GFO, carbon, or bio pellet reactor! After searching for reactors and being shocked how they can cost upwaords of 150-200$ for a tube i decided to try and build my own.. while in the dollar store i noticed a $3 glass pasta jar that was the perfect size for a reactor. The hardest part was finding the little bulkhead style pipe.. I found these lovely little bits at home hardware.  The circular mesh came from michales.  The red pvc i already had laying around.

One word of warning. The lids tend to be a bit thinner so be careful not to force and fittings as it may crack the lid.  I remedied this buy laying down a layer of epoxy (poly urathane) overtop of the lid to bond the cracsks and seal it all together.. If you drill it successffuly with out cracking it then i’m sure you can skip this step unless you want to strengthen the lid.  Either way its fairly low pressure inside and should not be an issue.

If using this as a diy carbon reactor I would use the sponges above and below to hold the carbon tightly and prevent tumbling.

If doing a DIY GFO reactor leave space above the gfo and adjust your flow so that the top just simmers.. you want some movement in the gfo doesnt bond together.
for DIY Bio pellet reactors just use the mesh screen and have high flow so the bio pellets are continuously churning in the chamber.
