Ahhh, ok: there's a difference. What you're talking about, the door is
hinged on the bottom, yes? The AS skimmer door is hinged from the top. Stuff
goes in, regardless. Personally, my pond is caged, so I don't have a leaf
problem or worries about things floating back out. All I get is algae and
little fish looking for a snack. And the fish scoot out real quick when the
want to!

Hmmm . . . I'll take your word for it, but I don't understand (not
the FIRST time, believe me!). F'rinstance, the skimmer opening is 4"
high. The door floats on the surface of the water level, inside the
box. If the pond is full, all 4" of space is filled with water. If
the water is low, maybe only 1 or 2" of water goes in, and the door
*still* floats on the surface. Why does it make a difference? (not
arguing, looking for enlightenment G)

It took me a while to see it, too.
The skimmer door floats on the surface of the water, thereby limiting
the amount of water that can enter the skimmer below the top of the
door. Yes, a bit can (and does) still enter around the edges of the
skimmer door, but the vast majority comes in /over/ the top of the
door. It's easily illustrated by using some suspended particulate
matter dropped in front of the skimmer both with and without the door
on. Without the door you may note that the flow is not as great and
the particles move toward the door from all depths at pretty much the
same rate. With the door attached and floating correctly the particles
move /rapidly/ on the surface and little or not at all at any depth.
The purpose of this is to keep the whole body of water cleaner by
skimming just the surface of the water. Gets the trash before it
drops to the bottom.
I had to actually /do/ this experiment before it fully took in my
excuse for a brain.
