Thanks guys, I appreciate the tips and suggestions while I was setting up the skimmer
Placing it inside the sump was an operation that would make Harry Houdini proud.
I had to detach the union in order to get first the skimmer body inside the sump, then the pump, and lastly reattach the union to the Mazzei.
After that was done I realized that the extension of the Mazzei was interfering with the drain pipe, so I ended up raising the skimmer about 4".
The fit is so tight that once in position both pump and skimmer won't even move
I was very impressed by the pump. It's practically dead silent even at max speed. I might get another one and use it in place of the Eheim.
The loudest sound in my sump is now the ATS.
The skimmer has been running for about 2 hours, the bubbles just now are beginning to touch the upper flange.
I had to adjust the gate valve closing it almost all the way at least for now, as raising the skimmer lowered the starting water level (according to the manual 1" from the top flange). Water level is about 1/4 - 1/2 inch below the outlet and about 9" from the sump bottom.
How long does it generally take before the foam starts traveling up to the cup?
