The deeper the outflow of the siphon standpipe, the more the pressure that has to be overcome to get the siphon started and purge the air from the pipe.

Ah, this is why sometimes it takes a while for the system to self regulate after restarting the system. I have my open pipe and emergency at the bottom of my sump, angled toward the side wall, only because I haven't trimmed them yet. I had a few extra inches of water in the sump and the system didn't adjust normally. Makes sense now. I will trim those as well. My system has only been running about a week.

On a side note, my gravity fed fuge which is tee'd off of the siphon tube stopped receiving diverted water all of a sudden. I have it designed so the 1" fuge line is at the bottom of the 1.5" siphon tee to ensure direct gravity flow (tee oriented vertically, while the side of the 1.5" siphon tee continues to my skimmer sump.
My guess is that the siphon was so stron, it was sucking all the water to the side hole of the tee not letting any water go straight down using gravity. I was able to adjust it by just slowing down the 1.5" siphon with the ballvalve I have about 12" below said tee. So far so good.
I'd just like to say thanks Bean for all the help you continue to provide for everyone.

Not a problem at all.
In all honesty, I would feed the fuge with a minijet or maxijet. They are only a few watts and have tremendous flow at low had. You then will not have to worry about keeping anything in tune.

that's what i was thinking of doing to adapt the three pipe design to melev's sump designs. Just have all three pipes flow into the skimmer section of the sump, over baffles into the return section, in the middle of the 55g sump. Then have a MJ 1200 or something pushing water from the return section in the the middle of the sump over a baffle to the fuge section, on the right side of the sump. That way i could have all three pipes from the overflow terminate at the exact same level in a sectino of the sump that will always have the same level of water.

remember, you don't need the "bubble tower" because there are no bubbles with this design.
Not sure about the sticker....

It will work either way, you just have to be aware of the backflow during a power outage.
I prefer to return over the top and drill the closed loops below the overflow box.

I think I am just going to go over the top .. I think that will be the easier route...
But here is some quick drawings.. will that be ok? If I have to trim the Street elbows in the overflow box I will.. just to be about 1/4" off the bottom of the box right?

You should be ok trimming 1/4" off (that is how my current setup is). Just be aware that the as the depth of the water decreases with regard to the intake, the likely hood of air being sucked in via vortex increases.

The water level in the overflow box is a function of the flow rate, the standpipe intake location and size and the ball valve setting. You can adjust it somewhat, but doing so changes the flow on the open channel standpipe as well. I.E. slowing the siphon by closing the valve raises the water level but also forces the open channel to handle more flow. With more flow, you need more air. More air means more bubbles and possible noise.
I would not go any close with the holes. 1.5 diameters apart is the closest i would make them.

It should be fine... make sure you can get your hand in it to clean out debris, macro, etc.

Hey Bean Great system, got mine running today and am very pleased when it runs right but I am experiencing one problem with it. The open channel wants to perform as the "main" drain most of the time when I start it up, of course that is not correct and rather noisy. I must have missed something in the setup, I only have one drain with a valve whidh is the siphon......heh,heh my face is getting red, it just switched over and became silent. I guest that's the part of setup I missed, is it supposed to start off on the open channel then switch over to the siphon?

The siphon will take a few minutes to fully kick in. All of the air must be cleared from it first. Shortening the submerged portion of the siphon standpipe will help a little if you are concerned about the time lenght of time it takes to purge.
