Tunze 9002 - No Bubbles

[Dorion]

Hi guys,

I am sorry to be bothering you since I know you are Tunze USA, and I am up here in good old Canada. But I received a Tunze 9002 DOC Skimmer for my RedSea Max 130D, and it seems to be having some issues.

I have had it in my tank for about 16 hours now, and I have 0 bubbles being produced. I have taken the unit apart and reassembled it to make sure everything was pointing in the right directions (nozzle on the pump was facing upward into what looks like a half bubble) and ensured that the airline was connected and not kinked, and still not a single bubble is forming.

Just wondering what you would suggest doing? I know there is a break in period for skimmers, but this unit should at least be producing some bubbles, and it almost seems like the water is barely circulating within the skimmer body.

I have been reading all night and found that there may have been a couple of faulty venturis produced recently, and I am wondering if mine may be affected by this.


Any help you can provide would be greatly appreciated.

Thanks again for the assistance!

Dan

Beyond any doubt it is the 9002.400 nozzle that needs to be replaced. Xenia or your dealer should be able to provide one. Since the pump is fairly small the nozzle has to be very precise and in the non working units the hole for the air intake is only about 1mm off of where it should be.

did you have do any modification to the RSM 130D to make the protein skimmer fit and are you getting any microbubbles in the tank?
