+1 dcan I had a bak pak 2 was ok until it started to leak. I tried for a day to get it to stop then I killed it because it pissed me off. When I took off the accelera pump from the thing the shaft on it had rust on it. Overall I think was the worst thing I have bought so far. 180 bucks down the drain that was the unit and bbx (bubble trap/surface skimmer) I have a hob fuge now from aqua traders the skimmers is ok on it. About as good as the bak pak (when it didnt leak) The pump isnt suppose to be very good but it has a ceramic shaft so no rust there. Eventually I will turn off that skimmer just run water through it and get a octopus 800s.
