At 35w and 9" that would probably be pretty close I would guess. Whether the wedge pipe is 95% closed or 95% open doesn't make a bit of difference, adjust it to where you want it and let it go. The high you go up with the speed of the pump the more you're going to need to open teh wedge pipe at the same height. Also, the deeper you set the skimmer in the sump the more open the wedge pipe is going to need to be and vice versa.
I'm getting a lot of water coming from the wedge pipe where the air hose goes in. To the point where it sounds like someone is peeing in my tank. I've tried adjusting the hose to seal the hole, but it's too much pressure. I figured it's because I have the wedge pipe almost completely closed. It's very annoying. I don't understand why they didn't put the silencer outside of the wedge pipe to prevent this. I've noticed some pictures online show the double cone 250 with the silencer at the top of the wedge and some show it separate from the pipe. Any idea why that is?
