If the water level drops to that hole when the power goes out and the siphon stops, it will not restart and you will overflow the tank.
Check the DIY Sticky thread for pipe flow rates.

tank plans look ok?

ok anyone have any good suggestions to have the suction tube at the bottom without haveing any problems.
Drilling the tank is a much better idea. If you want the overflow to pull water from underwater, not just the surface, you can use a double walled overflow chamber divider thing. Water still flows over the top, but you can also drill some holes into the lower part, so water flows in and then through the divider. That is how my 75G is made.
How do plants turn ammonia (NH3) into carbon dioxide (CO2) ?

That i dont know just heard they do something good for filtration. You have a picture or drawing of what your talking about. I believe i know what you mean.

They don't I goofed that point up :-D
　
Anaerobic bacteria, which is very difficult to achieve in freshwater tanks, convert nitrate into carbon dioxide, plants absorb ammonia/nitrite/nitrate... sorry for the mistake and thanks for catching it FSM...
　
　
And sorry I forgot to include my illustration for the intake I mentioned previously
　
　
　
As for your drawing on the other page (which I couldnt quote to repost for some reason)
　
On the intake side if the power goes out, or you turn off your pump during maintenance, the siphon will not restart and water will spill onto the floor This is why we drill tanks or use overflow boxes
　
On the return side, with a hole drilled in the bottom, if the power goes out, or you turn the pump off during maintenance, you have a hole in the bottom of a container full of water. So the water will drain out that hold
Drill a small hole in the intake pipe where you want the water level to remain when the power goes out. The small hole drilled in the pie will break the suction, yet not affect your filtration system. This also works well when yah end up turning off the pump to do maintenance.
If yah have the bttom drilled and the inlet is only a few inches from the bottom, take a pipe, white of black pvc, thatis the same diameter as the intake top caped small hole drilled where yah want the water level to be and connect it to the intake so that you have something like this...

Ok so a hole through the intake side will be for the water level lets say the power comes back on in the house. I'm not home now the pump is running and no water is siphoning now goin to overflow the tank and run pump dry. How do i keep that from happening.
Maybe i should just keep to the first idea??

Ok with some sleep and stuff ive finally understood this LOL sorry. Thanks for bearing with me. This should be the design. Intake tube at the bottom to help suck up most fallen debree, into the filtration meadia throught bio/scrubbies wet/dry into the refugium for possible plant life. (of course with a light that i have not drawn) into a 2100 gallon pump witch should turn me over lil more than 5X outlet for water back into tank pointed downwards to help flow debree to intake side of tank.
1.5" pvc by this site says that should be enough for gravity feed and enough for the pressure side of pump.http://flexpvc.com/WaterFlowBasedOnPipeSize.shtml
Please correct me anyone this time again i know im sorry but thanks alot. Should get a call on my acrylic Monday and start making tank.

Just throwing this into the mess of ideas and worries, the plants will need light, no matter how low light they are, just and extra expense
