What are my options here?

[Drew11]

So I took off one side of my overflow boxes because the silicone job was a disaster ( I bought the tank used). Come to find out it was a mess because on the sides of the overflow boxes they were splitting apart so they tried to seal the split with silicone. Anyway... what are my options:

Should I call LFS and ask them if they can make me another overflow box? (cant find anyplace that sells them, if you know please lmk, thanks)

Also in my pictures you can see what this style of overflow looks like, should I do some construction on it to make it a different style system? I think I could saw the pvc and attach more pvc to make the changes?

Tank is 125g standard dimensions.

That's what the other side looks like, and the overflow box I'd need.

Heres what it looks like behind the overflow baffle, this is the side I removed.

Could/should I make it into a durso ?

I used all four 1" bulkheads (the size of all the holes) for a dual syphon with two backups, then pumped water back over the top getting rid of the lockline for open elbows. At this point you could do about anything. One thing I would consider is installing a false back wall that would act as a coast to coast over the back overflow. In a smoke or black glass it would be a very sexy setup. You have a lot of options depending how involved you want to get.

So you're saying that you used both pipes on your dual overflow. Two (1 on each side) for your syphon and then what would be my return pipes I could make into a back up if the others fail?

I like the idea of a coast to coast overflow and thats something I'd like to do, but would/could I do it with the dual corner overflows already in place? Or would I need to take those out somehow so I would only have the coast to coast system?

I tied both overflow boxes together one syphon drawing from both sides; this way one box doesn't become stagnet. I don't use standpipes on the syphon, just the bulkheads. The other bulkhead in each box has a standpipe; I used an 1 1/2 PVC pipe with a 1" adapter for the bulkhead to recieve it. This is more or less a Herbie style as I try not have any trickle drain. When I plug one side of the syphon the emergency drain in that box picks up the work, and because the valve controlling the syphon isnt set for the greatly reduced flow the water in the other box drops way down as the syphon setting doesnt hold it back. If this were Bean it might have another 2 emergency drains, but I hate names; they are syphon drains with one or two backups, little more.

If I were to pull my overflows to build false over the back, I would start my planning with the syphon on one side and the back ups on the other thinking the plumbing might layout better, and work from there. I would price 1/4" glass with support ribs that run 3/4 of the height. I think a coast to coast like this could almost be a wash as far as cost goes when comparing to a trough style c2c considering the cost of additional plumbing parts. I also think it would look far sexier having the look of having no overflow box, and the sacrifice is the loss of a semi-useless space.

Ok so I found out that each overflow is rated for 400 GPH totaling 800 GPH for the system. What I was wondering is If I used acrylic sheets from TAP Plastics.com 1/4" thick, would that be okay to replace the overflow boxes? Should I use 2 sheets and piece them together to make a square overflow box in each corner or should I just use one piece of acrylic to make a "triangle shape" overflow in each corner? The reason I ask is cuz i dont know if one way is stronger than the other.

More info: AGA 125g tank dual corner overflows with 1" drains and 3/4" returns 400 gph in each corner. I have a mag 12 return pump.
