Does a protein skimmer use up more water?

Is that the thing that looks like a thermos? Blue and black?

I do have some green plant looking thing in the sump that is supposed to remove nitrates. Would that be the macro algae? I can get a picture.

Yes and no on the skimmer. I can have the height set just right, but if I turn it off then on, or add another gallon because the level in the sump has dropped, the level is not right any more and needs to be adjusted. But, since the lid on the sump was modified, that is a bit easier to do. It works great when it's set right! It's like emptying a potty toilet- boy does it stink! It has to be a good thing that all that 'crap' is out of the water.
