Hello people,

i've had a Tunze 9005 skimmer in my 20G nano tank. It has been working for years. It was cleaned in vinegar about a month ago.

About a week ago it stopped skimming but was still producing minimum foam. It did not reach the collecting cup

I took it out 3 days ago, took it appart and gave it a good clean. I found something was blocking the air intake. I put it back together and gave a good inspection.

Put it back in the tank and today i still have this minimum foam.......not reaching the collecting cup.

I can't believe such a thing but........can my tank be too clean?

It is a month old tank with my 2 clowns from the previous tank.

Thanks
