Tunze 9010 too loud

Hello,

Just bought new tunze 9010 skimmer for my 6 month skimmerless tank, works fine, producing 200 ml wet skimmate everyday. But one problem is really annoying... NOISE!!

The noise coming from skimmer is so loud I can hear it down the hall. The noise seems to be coming from the water pump.This is my first experience with a skimmer so i'm not sure if this is normal or not?

That is not normal, the video doesn't give me enough info. I would first be sure that the skimmer is not touching the sides of the tank, for example, the cup should not touch the rim. If you use magnet holders, make sure the rubber feet are on. This is important to isolate any vibration. Are you sure the pump is correct for your Hz and voltage? A 50Hz pump run on 60Hz will make a lot of noise, this would mainly be a concern if you imported the skimmer from another country. Also try opening the pump and check that the drive unit is in correctly, I do see sometimes that the bearing bush 3000.620 has moved in transport and is not all the way in, but this makes a louder noise than what you show.
 
With vibration there is no problem, this sound is going from the pump. With hertz I will check, but I think both in German and Lithuania is the same voltage and Hz. Now I will try to take the pump out and will see how it works in salt water itself without reactor, also will try to look for bearing bush 3000.620 .

Thank you very much for your help.
 
I've checked, everything seems to be ok, maybe I should follow the hydrofoamer manual, as I read it now on internet,

"Initial running noises will decrease
distinctly after a running-in period of one week
approximately."

Maybe this is a key to solution, as my skimmer is working only 2nd day, foam is good, produced about 200 ml light tea color skimmate.
 
A good customer and friend PM'd me that he had the same problem at first and that it is one of two things, the pump is not in far enough and is laying on the bottom plate, push the pump in as far as possible and turn it so it is sideways, so the thinnest part faces top and bottom. If not, it is the magnet holder, if the glass is thin you may need an additional pad of rubber.
 
Thank You, Roger. I re-assembled the unit, and now is ok with noise. Now only one question..microbubbles? they are everywhere. But as I read the manual , I should wait at least for two weeks as the unit is new ?
 
In this way it is set to recirculate and this reduces bubbles but the skimmer will be slightly less powerful and respond more slowly to pollutants, for the most part it will work the same, but instead of responding almost instantly to a pollutant it will work slowly over many hours removing a little at a time. As the skimmer settles in, you can slowly open the door. The basically sets it from recirculating 80% of the water to recirculating only 20%.
 
Thank you . After two weeks I can say that skimmer works very well, skimmate is dark despite the fact that Blue Air Screw is fully open.But the bubbles keep going all the time still. I can hope that after month or two they will dissapear. But I will be very happy if smb will insure me that he using/used the doc skimmer 9010 right in his aquarium and after a while all bubbles dissapeared, because I really want crystal view, it so nice, and when all tank full of bubbles...:(
 
It should not produce many bubbles, it is possible that it is an issue with the water chemistry causing the problem.

Please check if the bubbles increase the longer the light is on, so in morning is less bubbles than after the day of intense light. This would mean the oxygen level is very high.

Please check if the KH is above 14 dKH. If so their can be a saturation of C02.

Also, the skimmer should be in an area without a very strong current.

Adding some kinds of vitamins and algae killers as well as stress coat or colloids will also cause this.

I have used 9010's in tank before and normally you get only a few bubbles every few minutes and they are bigger and just float to the top.

Also, make sure the skimmer is assembled so the output of the pump is inside the clear pipe in the skimmer body, this could be a technical reason for the bubbles and also for the dark skimming, normally with the screw all the way open the skimmate will be very light.
 
Hmm I think the bubbles come all the time, despite morning/evening.
KH is ok, 8, there is no very strong current, reg additives I used aminoacid, but now I will stop to do this.

Only wanted to mention, that my tank was without skimmer for 8 months from the beginning. i used skimmerless setup with chem absorbent filtration in the bio-filter.

Could you give an example maybe of "make sure the skimmer is assembled so the output of the pump is inside the clear pipe in the skimmer body," maybe there is some pictures or smth ?

Supplements usually has the ability to make a skimmer go nut's. So not using them for the time being might be a good thing.

Again this is probably the reason that your experiencing such a high level of skim mate right off the bat.

Thanks. I can only hope that soon will be better.

The reason I put video is that I thought that maybe from type and amount of bubbles someone tell me is this aquarium water problem or skimmer assembling problem .

I several times tried to re-assemble the unit, and seems everything is ok. But maybe there is some tricky detail which I cannot notice.
 
Ragnarokas,

Try cutting your powerheads off for abit and see if the skimmer still produce's the bubble's outside the skimmer. Or you could try turning your bottom plate around to where the slit's are at the back of the skimmer as opposed to the front.

I presume you have the water level close to the wavy blue line correct?

hmm quite good idea, I will try to do this, and yes, the water line is as required.
 
I re-assembled the skimmer one again, and , unfortunately, it seems that after that it begin to produce even more microbubbles. all aquarium like snowglobe. But it seems that with skimmer should be everythink ok, I re-check every junction and connection. I am getting hopeless,:hammer: here is several photo, maybe you will advise me smth.

Ragnarokas,

Turn the motor block long ways as opposed to how you have it in pics 1 and 2. And reassemble try turning the air down once assembled.

hmmm dont know if I understand you correctly -to change the position of motor block isnt possible because there is only way to put in the motor block.

Interesting, that even after I turn off the Blue Air valve completely, the microbubbles keep coming with big flow.

Already thinking about changing skimmer ;//////
