Well Tony
I have a G4 that came with my tank i purchased a couple of years ago and i fired it up and it has been running in my sump for a week now and i can not get it pull hardley anything. I think i need to maybe get a new pump for it cause man is that thing noisey compared to my Bubble King.
I have not seen the Tunze in action. Golds just set one up on a new tank and was looking for some feedback. I love how small they are and they use very little power.
