i want to know what parts are you put in each box how are you going to make it work if you have it done i would like to see it runs to see how it works thanx

Excuse my ignorance, I see you have a 125 DT, but how large is your fuge/sump? I'm guessing it looks like a 30 or 40 gallon. Either way I think you should be fine. It looks as if you planned correctly when making your fuge/sump to incorporate the overflow. But as always, test it with a "planned" power outage to make sure it doesn't overflow.

It looks to me as if you are fine. Especially if you normal operating level is lower than the picture. I run a 55g DT with a 20g fuge and have no problems at all. My H20 level in my fuge is probably a little higher than your's looks and your system is twice the overall gallons mine is. So you should be fine, but plan a "power outage" and see if everthing is okay.

You should calc how much water is going to come out of the DT. Then make sure you have enough room in the sump. What are the dims on the DT and sump/fuge (H,W,D). How many inches does your DT lose when the return is off 1"-2"? When the power goes out the returns will reverse siphon and fill the sump/fuge. Give me the dims and I will show you how to calc it. Also I would put the return in the center and the fug on one side and the skimmer on the other and have them flow to the middle. this will allow both to get raw tank water and will be more efficient.

When the power goes out the returns will reverse siphon and fill the sump/fuge.
That is partially correct. It all depends upon how you set it up though. In the event of a power outage your DT will drain to either the top of your overflow, or the top of your return line in your DT from sump/fuge. Whichever is lower will be the point to which it drains.
But you could have a return line that is lower than your overflow intake, and it will still only drain to the top of your overflow. This is only if you put a hole in your return line right above your DT water level. This will allow air into your return line to break the siphon. In which case it will drain to the top of your overflow. That wasn't confusing was it?
To give you an idea of my system, I run a 55g DT with a 20g fuge. When the return pump is turned off my DT will drain about 2-3 extra gallons into my fuge. That being said, that the reason my 20g fuge normally operates with 15-16g, so it can incorporate the extra overflow.(2-3g in my system)

Also I see your fuge is 40g, and it looks like there is maybe 25g in it during normal operation. So this leaves room for another 15g. Your DT is a 125, so I'm guessing it would probably put 6-8 extra gallons into your fuge in the event of a power outage. But that amount all depends upon how you set it up. It looks to me as if you will be fine.

Reguardless of whether you have an anti siphon hole the water in the lines will end up in the sump. The anti-siphon hole should be just under the DT water level. If the water overruns the OF by 1" that water will end up in the sump. 1" out of the 125 will be 5.6 gals of water so with an anti-siphon add in the water in the lines call it 6 gals. This can be calc'd to see how many inches needed in the sump.
So Hurt is correct, But the point should be that this is easily calc'd and should not be left to a guess that my end up on the floor. If this is done prior to building the sump a maximium water volume can be obtained and backwash room.
