2,400 gallon Arapaima Gigas Tank by JohnPTC

  • We are currently upgrading MFK. thanks! -neo
From the first post:
"From the sump box with an independent pump, pumps water up to a 55 gallon barrel filled with bio bale and bio balls. Once full, it automatically siphons back to the sump, exposing the bio media to air as it refills."

How do you plumb the 55g drum to do this?
THANKS!
Propably a bell, as used in aquaponics setups
 
Sorry I meant bell siphon
