Advantage to 2 overflows?

I am beginning to plan for a 265 gallon reef build. It would be easier for me for the set up that I am trying to accomplish to have only one overflow on one side of the tank. My question is, Do I need 2 overflows? Is there an advantage to having 2 overflows opposed to just 1 using a greater gph rate?
 
I'm certainly not an expert here, but it seems to me most people I've heard from with dual overflows have a bit of a hard time balancing their systems. Singles appear to be much easier to tune.
 
Personally, and from here on out. I will never get a corner drilled RR tank again.

Which is why the 265 I am getting ready to get will be drilled and setup for a coast 2 coast type over flow and Beananimal drain out of it.

What are you thinking of getting?

I currently have a 90 gallon in wall tank which is a corner overflow using the Herbie overflow. I personally love the Herbie.

My plan is to keep the 90 gallon in wall to use as a display refugium for the 265 gallon which will sit to the right of it, I will then use all my current equipment (with a few upgrades) that is in the fish closet where the in wall 90 is sitting.

I was thinking of getting a single corner overflow for the 265 which would be easier to run the plumbing through the wall to the right with a short run to the sump.

How come you don't like the corner overflow? Check out my picture, I am totally open to suggestions, thanks.
 
With a 265 a single corner would not be enough flow, with standard holes.

I dont like the corners because of the flow I want and the skimming aspect of them. Something with a wider footprint, in the top instead of down the sides, would better suit me. So the 265 will be plumbed that way.

This is the tank I'm currently eyeballing, this guy seems to be having great success with the 2 corner overflows used as Herbies.

Yeah I used to follow that thread a good while ago.

I just reskimmed it and caught up on it too. (re-skimmed... hahahaha)

Yes he is. The 265 I am getting does not have corners. My 180 does. I do not like that each is not as balanced as I like, but I am just using it as a durso.

I have the ML265 dual overflow reef ready tank, and the dual overflows certainly can be made to work; though if I had to do it all over again, I would buy the tank without the corner overflows and do a C2C. BTW, guy in the thread you cite has set his drains up in a way I would not. Larger pipe should always be the open channel, and put screens on all the pipes (even if you also have a cover on the overflow).
 
I suppose it's possible your LFS would do it for you on a stock ML265; otherwise you're looking at either DiY or a custom tank. I think many folks here would just do it for themselves, though that requires some level of comfort with grinding holes.

Can I purchase just the c2c overflow?
 
Yes there are people and companies that make them. I am having one made now.

Check with your local reef club There is always someone that does acrylic.
