Is there a reason the method you mounted and/or is it the only install option to put the magnets on the *side* vs the back that only has the one piece of glass? One you tube video stated the *cup* was square (me not knowing, but assuming it can be turned for the surface skimming) ... if that is what you are referring to for best performance ???
And the one you have for sale is the reason I added it to my inquiry list [smilie=hi.gif]"]
While the skimmer cup is 3.5" x 3.5", The skimmer body is 3.5" x 4.3", with the cup all the way forward (offset from the magnets). The side compartments of the tank are about 4.5" square. When you have the skimmer mounted with the magnet on the back of the tank, , the front of the skimmer cup is only about .2" from the overflow, and the overflow tended to cause water to fall on top of the cup lid. By mounding it with the magnets on the side and it slid to the back half of the compartment, you then have .8" between the overflow wall and the skimmer... plenty of room for the water to pour into the compartment without splashing on top of the skimmer cup. I also wedged a piece of filter pad between the skimmer and overflow wall (just below the overflow) to reduce the noise of the water pouring in to the compartment.
