Help needed setting up tunze skimmer
Hey, i have a tunze skimmer(not sure what model) that i got from a guy when getting a tank from him. this skimmer came with no instructions or anything. below i will attach the picture. once u see the picture maybe u can answer some questions.

Will this skimmer be good enough for a 75 gallon tank and a 25 gallon sump?
How do i get it to start skimming?

In the picture there is a red line and a yellow line. the red line is where the water is up to in the sump and the yellow line is where the water is getting pushed up to with the tunze pump. it doesnt even look like its skimming its always at the bottom of the cup. how to i get it to skim.

thanks for ur help in advance.

It needs to be not so deep, raise it about 1.5" The Green cylinder with the air hose on it is supposed to plug onto the nipple below the venuri screw. It loks like one of the first 230 skimmers so it should be plenty for a 75.

the red line is where the where the sump water is up to andthe yellow line is where the green cylinder is. is that the right setup. whats the next step.

Turn the venturi screw clockwise, until fully closed. Plug the skimmer in, and then slowly open the venturi screw, 3 complete turns. It can take several days, to a week or two to break it in, so give it some time at this setting before making any adjustments to it.

That looks correct.
