Tunze Nano 9002 Skimmer - No bubbles
Has anyone purchased a Nano 9002 skimmer lately? I bought mine on Boxing Day. I had it running on my QT tank for the last three weeks. I do not get any bubbles at all from it. At first I thought it was just breaking in. Took it apart and checked to make sure the air line was not kinked or plugged. If I blow in the air tube, I do get bubbles. I think it is the venturi. Has anyone had this problem? Does anyone have a spare venturi in Edmonton, until I can get a new one? Thanks for the help. Leon

I don't have one of these, but there should be warranty on this
|
I got mine used it works great, maybe yours is defective?
|
Yes it is still under warranty, but they want me to ship it back (at my cost), and then hopefully get a replacement. In the meantime, my QT tank with two fish in it will be without a skimmer. I am trying to get them just to send out a replacement venturi asap. Thanks, Leon

i dont think you should have to pay the shipping for something that they sent you if its not working properly. but thats my opinion.
|
I know this may seem dumb but I'm going to ask. Is the hose connected to the top plate of the skimmer?

I have the same skimmer (got mine used ) and it has never had problems making bubbles . I have seen some post on bunk venturies on nano reef and the customer service rep sent the people new ventruris no questions asked .Your fish will be ok without a skimmer for a while my 50 gal has no skimmer and it does fine.

Disassemble the venturi. There's a small elbow that feeds air into the venturi - this can get calcified and not allow air through. If you had the water level too high and it sucked a lot of water into the venturi, this happens and clogs the air intake. You might be able to force a small amount of air through, but the force of the venturi isn't enough to suck air through.
I've had this happen on my old 9002 a bunch of times. Here's what the part looks like, and what the calcification can look like: http://i290.photobucket.com/albums/l...k/P3024447.jpg Soak it in vinegar for an hour and it should be good as new. EDIT: I just reread the post about backflow - do you have the venturi assembled backwards? |
