It's mostly parts from an old protein skimmer. I used a control valve from a hob refugium. I'm hoping the design of the holes intended for the venturi pump will give a good spinning action. I'm still working on the lid, I will probably have it piped out the top and 90 it directly back down. Still don't know if it will work and haven't decided what I would even put in it. I just like tinkering. So far it's cost me $3.60 that I paid for a filter screen.
Added a rio magnet to the reactor. I needed someway to make it height adjustable. Now just trying to figure out if I should make a top or just let it overflow.
