[soldier1911]

I wanna go 180 bb mostly sps. My question is with tunze which combo should I go with? I don't want to go closed loop so any suggestions would help. And yes I have searched

I'm going with the TZTS21

then I'm going to upgrade the power supplies at some piont
That will upgrade them to a TS24 model

I'd look into the Vortech Propeller pump. You might wait a bit...but it could be great...I'm probably going that route. ~Matt
