To degass the unit. There's quite a bit of sulfate (end product) built up while cycling the unit.
All the gases accumulate on the highest point on the reactor.
I ran the effluent hose through the top to see if I wouldn't have to degass it anymore, but it didn't work. The effluent would get clogged up really quick. This way is just a quick 5 second degassing and you don't have to fiddle with the effluent rate every time.
