Here we go... I have seen some people drill siphon beakes as shown here with the red arrow
The water will spray into the tank and if the pump stops the hole allows air in and breaks the siphon faster.

"If you have a sump then I would recommend having a refugia"
A refugia? Isn't refugia the plant that you put into the sump and regular tank to filter with?
Yea I meant an overflow box, it skims the top of the water :D
Travis I don't get how drilling a hole in the bottom of the plumbing would help syphon break. Even if said hole had a tube that was JUST slightly higher than the inlet to the main syphon, would the syphon restart after the power was on and water was filling up again. I see my setup right now ALMOST does this. Starts to trickle down the tube but I haven't tested to see if it would go to full syphon again...
So much knowledge needed, so little time.....

I will just give my warning that your system will flood, bulbs will burn out, and things will take continuous maintenance... get over it.

skyetone - no, a refugia is a separate "sump" that houses algaes that filter the water.
I hole where Travis's arrow is will break the syphon if its the power is lost. The diagram above is a return line, right?

Yes, the return line. I don't like this type of syphon break though. I think it's better to just leave room in the sump.

Sky if you would like to make a simple return I wouldn't even use a siphon if you take your main tank to home depot they will drill a hole in the top for you then you can just have an overflow that way you never worry about it all you need is a rubber seal and some PVC it's easy and foolproof this way only excess water is sent to the sump (pump on water flows pump off no water flows) only what your pump sends up comes down just be careful you use a pipe big enough to handle the amount of water coming into your tank. If you use 3/4 pipe from the sump at least use 1" for the return to the sump. If you can't take your tank to the depot you could make a return tank IE you siphon water into a small 1/4 gallon tank hidden to the side or behind your tank then water flows out of that tank by a hole in the side of it just like is stated above. You could make a simple one out of plexi-glass for $5 and save you all the hassles of overrunning your tank or sump in case of a poweroutage. You may need to drill a hole in the pipe going from your sump to your tank so it won't siphon if power goes out.

just to clarify with this system the only water to siphon is what is below your exiting pipe this is a simple way to fix peoples siphoning problems

jglover, it can be even easier than making an acrylic box. Just buy a Lee's Specimin box from the LFS (the box the LFS puts the fish in after they catch it for you). It already has a hook for hanging on the tank. Also, if the exit from the overflow box is coming up from the bottom, a piece of pvc pipe can be cut to any length so you can control the tank water level. Your drawing is much better than my illustration in my descriptive article that is available upon request via
email.
