Thank you being polite and not trying to tell me how it would not work. You have some very solid points that I will take note of. Thank you for following. No one said it would be easy and I am definitely new to the entire process.

I never feel bad about admitting I'm wrong, when I am wrong. I was mostly wrong, I admit. This is why I ask questions and do tests. I put the end of the pipe into water and they miracles of science did take over. It did syphon the larger container. I learned something and was amazed to say the least. However, I drilled a hole in the pipe at the top as a test and that cured the syphon problem. I will now install a T with cap and hole to act as a break. I still like it and will use a modified version probably not so deep. I just now need to figure how many to use to handle a 3100 gph pump. It's looking like 4. The struggle continues.................haha

It's tough to do a back of the envelope calculation on your design. A vertical 3' section of 2" pipe can free flow (turbulent flow, not a siphon) at around 12,000gph. That's with no bends or other resistances.
You'd have to figure out the force of the water and then back out the force the route back up takes out. Plus the resistance the air intake adds and the resistance of the water hitting the water in the sump. Pfft! Too many variables for me at 5:30pm.

It is only a hobby Homer, but a very expensive one, that deals with living creatures.Your other hobby you just replace broken parts and keep the R/C going. Especially a 300gal full of SPS. I'd hate to see your invention fail trying to do something new with no proof of it working properly.
There are many unanswered questions and in my honest opinion surface skimming is essential in reef aquariums.[emoji4]

Its going to drain out to the strainer. Take into consideration the weight of the water in the tank. Gravity will force the water through the pipe until the force reduces and the water weight can no long overcome gravity. Its like a drain in a sink or toilet it traps the water and sits there until you add more water

Sorry but this is not new as I've done this before and a few other low profile setups and could not get the results so trashed it. Loud/siphoning/gargling/pipe not draining after power off and back on and a bunch of other problems I encountered when trying this. Wish I saw this thread before I could have saved you the time

Ok how would you guys set this up. I would love to hear your thoughts. I have a lot of patience and am in hurry to mess anything up.

Well it seems that your goal is to have little to no visible plumbing in the tank. I would recommend an external coast to coast style overflow with a bean animal drain system. I have that on my 130g and it is 99% silent extremely efficient and I have no overflow or drain plumbing in the tank at all. If your tank is already built, but still needs to be drilled, then I would do a ghost overflow. They have minimal in tank footprint and are still set up with a bean style drain system and run silent and failsafe.

Do you have any pictures of this setup. thank you for answering.

If you're looking for unobtrusive, I think the external bean animal is probably your best bet. If you do a long internal weir and make it the same color as the back of the tank, you won't even notice it. They only come in an inch or so.
Just make sure you leave 3" or so on either end so you can clean the side glass next to it.

Thanks. Looking at pictures of coast to coast stuff. It's a very nice set up. I've been rethinking all night.

You can even buy the boxes from vendors on here or eBay. Nice thing about them is that they're pretty bullet proof. A lot has to go wrong for them to cause a flood. It's the next generation design after a herbie.

Look at my build thread. Link is below in my signature. My tank is 48" wide and the overflow is 24" x 5". I hate seeing pumps and plumbing in a tank so this is why I did it this way. I do have two returns in the tank but that is pretty much unavoidable.
