Seems like a silly design, why put that baffle in at all?Water will not flow over the top of the 1st baffle in normal use. The top is higher than the bottom of the slots in the 2nd baffle. Both chambers will be at the same water level.

As I understand it the baffle before the third chamber controls the water level in the first two. Ok.
I suppose you could get better skimming with this design since the surface water in chamber 1 is staying longer.
Asking because I have a sump kit I've yet to put together and it's set up this way. I'm contemplating getting two pieces of acrylic cut to replace the first baffle - water flow over the first then down and under the second.
Well everyone is going to have different tastes to what they feel is "the way it should be done" even if there are more than one way to have it done. I'm not a fan of what is shown because that to me almost tells me I need to have a stand for my skimmer otherwise it'll be in water that too deep, and I like my refugium section to be tall so having water go over the baffle is my preference. I have seen quite a few "through" designs though, and again... just not the way I would want it done. A reason I like the adjustable baffle idea in the 2nd chamber so I can adjust water to the height I need for whatever skimmer I get.
Prove it! Where’s the tank journal?That is indeed a very popular sump on the market today. With the idea of drain>fuge>skimmer>return. You can get two small pieces of acrylic, drill hole on the acrylic pieces, put them on each side of that 1st divider then screw them together, that will help raise water lever to overflow to the top from 1st to 2nd chamber with out damage to the sump. Add a skimmer stand then you be fine. That what I have right now.
Only way that would work is if the water level in the 2nd chamber is lower than the water level in the 1st. So the over the top baffle in the 1st chamber will need to be higher than the water level in the 2nd chamber.
