Tunze 9002 - still not skimming..

[Nano]

ok.. facepalm...

I might be completely brain dead but here goes,

after reading around and finding people having similar problems, I`ve discovered maybe the pump is in backwards so to speak but cant find a good diagram on how it should go so I`m sketching up how I received it and have run it for the past year, as well as how I just read its supposed to be run, anyone who knows please let me know ASAP
thanks

so this is how I`ve run it cause thats how it came


This is what I`m reading its supposed to be set up like... is this correct or am i reading it wrong??




Thanks in advance I feel like a dummy :P
