Holes should be kept at leat 1 diameter ( I prefer 1.5) apart.
Twisty, that product is just a suitable type of pad I found at mcmaster, you can use anything similar.

The silicon pads I made worked well but I had problems with them coming loose in the sump, and they were hard to situate.
I'm trying one more thing before I buy something... I silconed over the eggcrate, and will see if that helps. I'm a little nervous to dump basically a block of silicon into the sump though.
Should I worry about silicon leeching anything into the water...?

Bean,
Getting a 5' wide tank and was thinking of doing the coast to coast overflow. Now that I see your setup for the stand pipes, I am thinking of doing the same.
My flow is going to be between 800-1000 gph through the overflow. I'd like to make the coast to coast as narrow and short as possible. What can I get away with for size? Also would like to run 1" all the way from the bulkhead to the sump. With the flow I am looking at would this be possible instead of the 1.5"?
Thanks.

Chichas,
In my opinion it is essential to setup the system with 3 standpipes. Using two standpipes leaves you vulnerable to flooding. In any case, the second standpipe needs to be setup to assist the first. If you try to run a stright siphon on the first standpipe and a dry second standpipe, you will be constantly adjusting it.

You can get away with as short as you are comfortable with. Just keep in mind that the longer the weir, the thinner the sheet of water and the better the surface skimming.
I would imagine that you could get away with 1" pipe for the flow range you are looking at, but as mentioned above, the 1" pipe does not allow for much air in the open channel standpipe. The narrow pipe will gurgle at a much lower flow than the 1.5" pipe.

Welcome to the next level
gbsteve, I am currently underway with a 5' 120 gallon tank build and I have made a "low-profile" acrylic overflow box. The box is 2 1/4" Deep (off of the back glass) and is 36" L x 3" T. I had to cut the elbows down a bit to make them work. Its virtually invisible inside of the tank.
I also thought about running 1" PVC through out the system but Bean's advice made me re-think this and I went with 1.5". Just be prepared to SPEND when it comes to ordering your quality ball-valves in 1.5" (Im using Spears Valves = $$$)

Welcome to the next level
I have actually cut this down a bit to make it even more "low-profile" but you get the idea. I went with the "toothless" design to allow better skimming.
I will get some more recent pics later.
Sorry if I was confusing Bean. I will be having a coast to coast or at least 3' wide overflow. I was thinking when I said short, about the height. I see meuser made one 3" tall, that is what I am looking for.
What kind of silent flow could I expect out of the 1"? Just don't want to really cut a bigger hole in the floor to the basement!

If you make it too short, the intakes will create a vortex and suck in air 
I am not sure what kind of flow you can expect out of the open channel standpipe if it is 1" but seeing that it will drop to the basement, I would suggest going with the larger pipe. A long drop and a narrow pipe is asking for turbulance and gurgling even at a modestly low flow.

Ok I havent seen any mention of it in the thread yet so I will ask.
how will this work with a wavebox?
my current plan is to have a large overflow box with said silent standpipe setup at one end of a peninsula...BUT at the same side as the overflow I want to put a wave box.
Im wondering how a 3/4" to 1/5" wave will effect the system.

Nice CAD drawings, especially those true union ball valves!
Looks like a modified version Herbie Overflow method or a hybrid mix between the Herbie Overflow method and the Durso setup.
It just seems you've added on a lot of complication to the setup though, even more so then the Herbie method. Then again it's hard to implement the Herbie method if you don't have a deep overflow box.
I bet it works like a dream though.
Peace,
John

I did not draw the valves, I downloaded them from the manufacturers website. I don't think I have the patience of skills to draw a valve with that much detail.
People keep mentioning "complication". There is really nothing at all complicated about the setup It is 3 standpipes, 1 with a ball valve and 1 with an airline fitting
Yes, it works like a dream. It is dead silent and I can sleep well knowing that my overflow will never cause a flood.
