Help with sump baffle sizes?

[Sonor]

One think you should keep in mind. What is the recommended water level for your skimmer operation. You might have to build a stand for it to achieve this water level. If you do make sure you have enough clearance in your cabinet to do maintenance. Or just cut down the baffle A, to the water level that you need.

Hi All,
I'm new to sumps, having run a Red Sea Max 250 since I got into the hobby nearly 10 years ago. I'm starting up a 120 gallon (4x2x2 bottom drilled with overflow in the back center) and have a 40 breeder sump. I had a guy build my sump and he did a crappy job. He used black silicone and it's all over the place. And the first baffle is 5" higher than the 2nd chamber - won't that create a loud waterfall? What should the height difference be (and still be okay for most skimmers)?

I'm going to remove the baffles and redo the silicone in them and possibly move them. I like having a good amount of water in that first chamber, but should I reduce the height of the first chamber? Does everything else check out okay, or should I make more room in the return pump chamber?

Also, should B and D be the same height? He actually has D slightly higher than B, and I imagine if anything that B should be higher?

Oh, I don't know yet what skimmer I'll be using. I have a Jebao DCQ-10000 DC return pump (which will also be feeding an algae scrubber sitting on top of the sump). Thanks,

That would be gravity not overflo
