Help! Berlin 90 adjustment

[bigolhorns]

Just put a Berlin 90 air lift in my 60 gallon tank. The instuctions are lousy. How do you adjust it? If I turn my air pump up it fills the cup with water in about 20 seconds. If I turn the air down no foam reaches the top of the cup. What am I doing wrong?
Thanks for your help!

I have a Berlin 90 also..
You have to make sure the airstone is close to the bottom of it, and also if the stone is new, its gonna be alittle different then when its in there for awhile...'
Is the stuff comming up just water??
The way we adjust ours is to have a little *cyclone* in the tube..instead of a monster twister..
Hope that helps you....

What brand and size air pump do you use on the airlift 60?? I'm considering buying one for a 35g.

There isn't an air adjustment where I get the "brown liquid". Any amount of foam going into the cup will fill the cup with water in a short time. I think I'll return it and get a Prizm.

Thanks for the help! I think I've got it. The skiimer is producing small amounts of liquid. Should the liquid in the cup look like beer? <img src="graemlins//confused.gif" border="0" alt="[confused]" />
