I have being using the 2000 for 2 + years driving my co2 reactor and it still runs quiet & operates like the day it came out of the box
It's in a 29G sump that is for a 40b. However, I intentionally over did it on the sump and return thinking I'll just move that over to a bigger tank at some point.Thanks! BraveBuc, what size tank and sump are you running? How is the flow?
