My Tunze DOC skimmer 9010

[janmadsen]

I startede running this skimmer in my sump 2 days ago, and there is coming a lot of very very fine bubbels (microbubbels) out of the outtake pipe, and I have the sponge on - but it doesn´t help. Is there anyting I can do about that?

Is the skimmer working normally otherwise? The velocity of water coming out of the pipe should be so slow I cannot imagine that bubbles would escape after the sponge. I think something is connected wrong or the water contains some sort of colloid additive that is increasing the bubble retention.

I think the skimmer i working normally, maybe it is the water - the tank has only been up and running for at week.

Thanks!
