Tunze 9002 - still not skimming..
 

So my skimmer has been on the fritz for months now, probably causing or adding to some of the problems in my tank. I recently discovered the power cord was cracked causing it to stop and start etc. So I replaced the motor yesterday.

While I know it can take a bit for it to start producing, it doesn't look right. It's producing the fine bubbles typical of the 9002, but they arent even reaching an inch into the neck.. even after 24 hours it should start to bubble a bit higher, but hasn't. I'm not sure what's wrong at this point, I have disassembled it yesterday, clean the clear elbow that attaches the airline to the venturi pump, but it seems like the bubbles are bursting before the collection cup. I'm not sure if the motor is sitting to high, the skimmer is at the right depth, but nothing is happening.

Anyone with tunzes or experience with them your help is appreciated.
I need to get this thing back on line asap.

Thanks

I'm sure you have already tried adjusting the air valve?
Also in reading p on these guys I have seen a couple posts regarding issues with the air adjustment and they have been modded to be more effective.

Yea mines been modified as well, it worked great til the motor crapped out, now I've just been losing hair over it. Lol

Well the only other thing I can think is that you may need to change the water line a bit to get the bubbles climbing to the necessary height. Then again I know sometimes my skimmer will go days without producing any skim mate even though most of the time it runs extremely efficient.

Are you running the 9002?

I've always found mine worked well at the specified height til now.

I had some issues with my Tunze as well after about 6 mnths. I had to take the whole thing apart and clean out the airline and the connecting elbow as well as the motor and impeller really well. After that it worked fine again.

No. Sorry to be misleading if I was. I am just in the process of setting up a small cube and have been reading the Internet in its entirety on different options.
I am running a reef octopus on my current system.

Yeah i just did that 2 weeks ago, when I put the new pump in last night i inspected it, and its still clean

heres a video showing what its doing.. er.. rather not doing
you can see the bubbles not even reaching to the bottom of the cup (which is a bit dirty on the inside, but the neck is clean)
usually after cleaning the skimmer, its working or at least starting to within a few hours. so again, the neck of the skimmer is clean, the cup is dirty on the inside though. I doubt that would be the cause. I have opened up the air a bit more since filming this, so we'll see if it helps.

Any ideas?
Since opening the airline a bit the bubbles are just below the cup and look a bit finer. But I don't know if with a new motor I'm going to see an extended break in period or if something isnt right?
Again any help is appreciated..
