The return line will have a check valve closer to the sump to limit flow that way. My Durso will limit any further flow from the top. My inlet line volume will be the problem I think from the dt. There is a gap of three mills on top of the highest baffles which will allow for some spill over to each chamber but any more than that it will be soggy....

If I understand your sump, in the picture, the left is the drain from the tank, then the right is the return to tank. If that is the case, just remove the 3rd baffle (counting left to right) and cut it down. I leave my sump at 9" and I think most make them 8" to 10" as recommended for most skimmers. So again, just remove that third baffle and get it cut down to 9" or so, then re-silicone it in place and you will be rocking.
So water enters on the right side in the picture. Ok, if that is the case, remove and cut down the first baffle (if looking at the pic from left to right) or the last baffle in the sump. The blue line is where your water level would be through the sump. Cut down the baffle marked in purple. I would still stick to 8-10", nice if you want to do a small fuge or even just frag rack down there.

Sorry....The right side of the tank where water enters it flows under the baffle then like torx said for left side it flows up and over the baffle. If I need to cut the left side baffle would I need to cut that same baffle down for the right side one to make it similar? I don't mean to confuse this!! The one I mean is third baffle from the left.

You don't "need" to cut the third baffle. But I personally would. The water may have a bit of a distance to fall and may cause small bubbles and because of the small size of the sump. The bubble will probable make it to the return pump and into the tank.
I'd personally cut all your baffles down. 3mm from the top of the highest baffle to the top of the sump doesn't sound like much room for overflowing water if say your filter floss would plug. If you're going through the trouble of taking one baffle out. You may as well take them all out and trim them back a bit. Just my opinion and what I'd do. But it may work just fine

Good to hear! You'll have a lot less troubles after it's trimmed.
What are the measurements of the sump, baffles, and your spacing. Spacing the baffles is just as important. Keep in mind that if you're going to be pushing close to 1000 gph, the water might just be rushing under and over those baffles. Which could cause a lot turbulence if you're planning a small fuge or frag zone.
