180gal tank overflow where to drill

Hi guys, I am planning to order a new 180 gal tank, however they said they would have to overflows in the corners drilled at the bottom. But I am planning to have my sump setup on the other side of the wall (not below the tank). Sump will probably start somewhere in the middle of the tank level. So should I ask them to drill on the side instead ? as if they drill at the bottom the return pipe would have to go back up to reach the sump.
 
I wouldn't purchase any tank with corner overflows..
Coast-coast overflow with a bean animal drain system is the ONLY way to go IMO..

It certainly sounds like you do NOT want bottom drilled holes based on your proposed sump layout..

Thanks never heard of those, I am just getting back into the hobby after 5 years of pause. Sounds very promising from what I see, maybe I should get one of those and ask them to drill for it
 
Thank you guys. To confirm . Coast to coast and shadow overflow are two different concepts?

Also for coasr to coasr overflow i see i have to cut the glass at the top correct?

No need to cut..
A coast to coast is simply placing 2 pieces of glass in a L shape right over the bulkhead holes in the back..

Now thats an "internal" coast-coast.. You can also cut the glass at the top so its ~1" or so lower than the rest of the glass then put the box/plumbing on the outside of the tank..

Multiple ways to do it..

And yes there are a few types of overflows that are basically the coast-coast concept (just might not be the FULL length of the back of the tank)..
But the more length you get the more it will consistently pull the protein film layer down into the overflow and not sit there floating on your water.

Any website with the plans you might know so I can give them exactly what I need
 
Hi guys, so the manufacturer suggested this setup for me:

So I think this is ghost overflow similar to the coast to coast. I think it will also have 3 standing pipes inside (will confirm that).

My question is, about the standing pipes. In the setup on the picture can I have 90 degree corner right below the overlow ? As I said I want my sump on the other side of the back wall, so I need a 90 corner pipe to turn flow to the sump that is located on the side. What do you think ?
