Planeden Posted May 12, 2013 Share Posted May 12, 2013 Hi all, I recently got two tunze nano 6045 powerheads and put them in the freshwater version of my reef tank (3-4 days ago. I think it is just one of them, but maybe 4 times an hour it sounds like it is "squirting" and a bunch of air bubble come out. I guess another way to discribe the sound would be a pump sucking in a little air. But it is constantly underwater. Could this just be part of the break in period, or do I need to be concerned that I got a bad powerhead? Thanks for any help. Link to comment Share on other sites More sharing options...
offroadodge Posted May 12, 2013 Share Posted May 12, 2013 if its set to high to the surface of the water it will create a vortek, like a tornado in the water an suck air. my 6105s do it when I drain the tank down for a water change Link to comment Share on other sites More sharing options...
ckyuv Posted May 12, 2013 Share Posted May 12, 2013 Yeah try lowering the power head or turn it down a bit, its sucking air from the surface and making a small whirlpool above it lol Link to comment Share on other sites More sharing options...
