Tunze 9006 skimmer

[clownfish_forever]

Hi bro,

Need some advice on Tunze 9006 skimmer.

Just acquired one and was trying to set it up in my sump. Can see the photo attached.

I just installed it happily in my sump and powered on .... and no foam ...

The manual mentioned to open the air screw by turning it 3 full rounds for the first 24 - 72 hours so I have done that (red circle marks the air screw)

As you can see obviously the water is below the recommended level. Not sure if it will affect whether there is no foam yet?

Or is this normal and I just need to power it on and let the skimmer settle in?

Since there is no foam, I am worried that the skimmer is not working properly so I am turning it off at the moment.

Thank you for any advice.

I realised that I am missing the extension kit needed for sump operation so I have bought and installed the skimmer exactly based on manual. BUT...after powering the skimmer, I definitely hear the skimmer 'boiling' but I dont even see the water level being pushed up... Is it supposed to push up the water level and then foam will form eventually?

I took a photo of the skimmer 'boiling' but can see the boiling is happening quite low the chamber. My water level is around 5 inches which is higher than 3.9 inches minimum as stated in manual.

Is this normal and I simply have to wait? HELP...lol

Hi Jeff,

Your water level is too low already, it has to be just right above the TUNZE logo in your picture, so i think you can't fix it at the last compartment already.

I am using my twin pump Tunze for 8 years already.. needless to say, German product last..

Hi Jeff,

I am using my twin doc Tunze for 8 years already.. needless to say, German product last..

Thanks! The odd thing is that when I refer to the manual, it says for sump operation, minimum is 3.9 inches...

I have looked up some website and they also said the same stories - if in main tank, need to be near Tunze marking...if in sump, use extension kit and water level can be lower.

Are you also using it in your sump?

[chrislwp]

Yes I am using in sump. Maybe yours is a new/different design, as mine already a decade which indicate the water level has to be high up to the Logo.

Why not try to put the skimmer in a pail, fill with your tank water up to the Tunze logo area and experience it. I can see your bubble is fine, means working well. The air valve allows you to tune the size of the bubble.

Not sure if my deduction is right, refer to the manual Page 21 of www.tunze.com/fileadmin/gebrauchsanleitungen/x9011.8888.pdf, it says

"designed for an immersion depth of between 240 and 290 mm (9.4 and 11.4 in)." Does it mean the depth of water range?

Thanks! I will try out the pail method.

As for the manual, ya...I saw that page 21 but that was for operation in aquarium.

If you see page 45, "In aquarium cabinets, the Comline DOC skimmers permit a very effective skimming process in a small space; they can be positioned discreetly in a corner of the cabinet. They are insensitive to differences in water levels from 100 to 280 mm (3.9 to 11 in.)".

And page 46 has an image too *confused*

Hooray! Problem resolved...sigh...figured out the hydrofoamer is not at the right position. Now the skimmer is running with 100% efficiency...tons of relief
