thanks for the info. When i get around to actually building this monster, everything is going to be big. It will likely be in the 500-1000 gallon range, so the pipes are gonna be huge. Not worried about co2 since it wont be a planted tank, persay. Maybe some willow moss since its native to Ohio, but any other vegetation will be strictly riparian. The goal is to put a slice of central ohio streams right in the wall of my home. The best part is i get to catch all the fish.
It may seem a little far fetched but this is my dream tank and really my only hobby that costs me money besides fishin' lol. I love our native fish and love catching them. even if i cant keep them right now, snorkeling in rivers with nets all day is a blast and something i do every summer Gonna be a long time before it can be achieved but when it does.... its gonna be EPIC.

FOR PIECE OF MIND
i've been doing some research myself
do NOT be fooled into thinking a 1 inch drain line is enough. OVERSIZE
look up. myth of the one inch beats on google
and also bulkhead flow rates
wetwebmedia has some good writeups. AND i've found they are true. my overflow is sooooo much louder on my 75 gallon UNTIL i get the flow rates down to around the 300 gph range. same as my 29 gallon
this can be done with ball valve or by swapping pumps..
not only that but its killing my co2 consumption
so ima shoot for a 1.5 inch drain which should allow for a safe gravity siphon, with low noise, and less air actually being forced into my sump.. should result in less co2 loss, less, noise, and the same oxygenation benefits
i throttled back the 29 about 50 gph so that the line doesn't suck in tons of air, my co2 consumption dropped in HALF so, when ur building. GO BIG ON DRAIN LINES

Yeah I think thats what he meant. If using a diy overflow the T off the rise of the low U would be where the high U is in that pic.
After looking at the various styles of overflow, I think beananimal's provides the most peace of mind and would probably work for what im trying to achieve. The overflow wouldnt be very large and could be easily disguised or just framed out of sight if the tank ends up being in wall. A small price to pay for keeping a couple hundred gallons of water off the floor. As long as the tank isnt too tall, I could use a Calflo style overflow, but have it spanning the width instead of the length. The tank will likely be 72x30x18? Not sure on height yet but it wont be extremely deep and that much width should give a good amount of pull. I could always design the interior to have a lower flow area like a pool on that side. I know thats a complete 360 from the original idea but it will be a lot safer and probably easier. Not too mention quiet.
Guess I should have listened to blazingwolf in the first place lol

I don't have any personal experience with sumps, but I'm planning on using one with my next setup, and have been reading around a bit.
One thing I've seen is that people hook up the venturi from a powerhead to the top of the siphon, or use some sort of low flow-rate peristaltic pump (I've heard 'aqualifter' mentioned fairly often, but the reviews I've read of it aren't too hot...).
This serves two purposes, to eliminate bubble/gas accumulation in the siphon, and also to help prime the siphon after a power failure.
-power fails, pumps shut off, water drains below hole for siphon break, siphon breaks, excess water drains into sump, everything stops, no flooding, etc.
-power comes back on. the pumps start again, but have little/no water available due to overflows/etc, aqualifter/venturi starts pumping the air out of the broken siphon and priming it, once siphon is primed, waterflow returns to normal and the system can effectively self restart.
I'm not sure if there will be much of a problem with the pump potentially running dry until the siphon is primed again, but it seems this plan is fairly common, so I imagine someone has some experience with it.

It is a closed loop not conected to the sump at all. Drains on one end going straight to a pump and discharge on the other velosity set by the pump and valve.

|kwheeler91||A monsterfishkeeper member said that I could use a bulk head and simply raise the T leading to the sump at the desired water level and it wouldnt drain any farther than the T. Doesnt sound right to ne but would that work?|

|HD Blazingwolf||It will not.. for it to drain, the valve will have to be open, so in the event of power loss, it will continue to drain until the siphon is broken|

I guess i would just have to experiment with intake heights and see if the higher mount is acceptable.
I know not all the species like super fast current, but i intend on designing the tank to accomodate for a few different type of habitat. There will be a riffles section and also pool areas that will have shelter the water will have to flow over and around, i just want to make sure the current hasnt died out by the time it surpasses all obstacles.
I may be worrying to much, but i really do want mupltiple drain heights.
Anyone know if the one way valve on the intake would work?

and u cna still setup the sump to have fresh water brought in, at any rate you like
i understand streams have decent water movement, but have u ever gauged what that speed is? its actually not that fast, the problem with streams and what makes them seem so fast is the VOLUME of water.. that's what gievs it that pulling feeling
also not, most fish that inhabit these streams have huge rocks or roots to hide behind to allow their bodies to rest, your flow is going to get bounced around a little, no matter how you go about it
