Currently, I've got a 30 gallon. But I would like to upgrade to a 100 gallon eventually. I've seen a decent guide for making a canister out of pvc
piping, which makes sense because they're made for water anyway. It utilizes a siphon effect so there's miminal load on the pump.
Really I want to know how I can tell or where I can find info on the amount of medi ill need and the gollans per hour the pump needs to be.
I still have a lot of research to do before building it, this is just a part of that, so please brutal honesty is appreciated.
