Comments: I have now had this pump for 4 years and it is still working great. I would recommend this to anyone. Anything I look into new equipment I always check out what Tunze has to offer since this pump has been such great quality.
Not so silent

Comments: Bought this pump because it was supposed to be very quiet. It is in fact not quiet at all - it has the vibrations of a small handtool and consequantially the whole display emits a droning hum which very much takes away from the beauty. Very disappointed with this products mislaeding claim of 'silence'.
One benefit of the pump - variable flow easily adjustable.

Comments: I bought this pump to run NP pearls in a Two little fishies 550 phosban reactor which it does very well. Really impressed with the fact that I can't hear it and that I didn't notice any increased heat gain in my tank. I'm actully going to be ordering another one in the coming months for another build I'm going to do, :).

Comments: I had to slow it down some. Great flow and not much sound. I will be using Tunze pump for now on.
good, quiet little pump

Comments: I use this pump for my auto-topoff. It starts up everytime without issue and while noise isn't an issue for a pump that only runs 20 - 30 seconds a day, even without the suction cups and sitting on the bottom of the plastic bucket, it's still very quiet!
