After closer look at first pic doesn't look like the ae tech skimmer I had unless it was modified

I haven't been able to find a picture of my skimmer anywhere..

That skimmer is an external skimmer, I had one a number of years back

External? With the pump underneath it? Can you find the vid?

Guy I got it from said it could be either external or internal..

After looking at the first picture again I had realized my error. My bad!

My DIY fractionating impeller works well. I tested with clean freshwater so no foam, but it does bubble quite well. Now I just have to add an air valve to control air flow. Because I'm not gonna hold my finders on the air hose forever.. haha

Ok so the input of my skimmer is bigger than 3/4" but smaller than 1" what to do?
