Closed loop or powerheads?
I have been looking over forums for days trying to decide which to go with. I am concerned more with long term operating costs, and the most productive. This is for a prop system. Right now it will consist of 2 50 gallon rubbermaid stock tanks and a 100g sump. It seems like powerheads (tunze 6025s?) would be cheaper to run consuming only 7 watts. Also less worry of bulkheads failing and getting a closed loop set up right. If anyone has some input please let me know. Thanks!
