Just a thought but what if you lowered the water about 3 -5 inches? You think it will be the same?
Will try that!

What if you added a fourth vertical baffle? This might be enough to throw off whatever is aligning so well to create the wave. I don't know how you could set one up temporarily to test it, though.

Hey Osprey, do you think you have air in the line? Have you tried just turning it off and starting it back up after a minute?
I think the problem comes from the fact that the 2 last "over" baffles are both at 16". The second one should be lower so the water flows/ falls over. You are forcing the water up and over the second baffle. My guess this is what is creating the wave.
Not sure the quickest way to test this theory.

The minimum water level is usually at the point where the pump intake create a whirlpool and starts sucking air.
I have an idea to test my theory. Cut a piece of old scrap acrylic that is the same width as your baffles and only about 3 in tall.
Then use a clamp and clamp it to the first 'Over' baffle so that is raises that baffle by 1/2 and inch to an inch.
You should notice the surging stopping right away.
If this is the case then there are several methods for lowering the second 'Over' baffle without having to tear it out.

I think you have the reason for the waves. All the baffles are the same height across the length of the sump. Raising the over baffle on the left side causes more water on the right side of the sump to have to push up and over creating the wave.
Each sequential 'over' baffle should be lower than the prior one.
Now change this sump design to be located over your tank and you might be able to build a cool and unique surge system![]()
That's what I just said lol...
Looks good! You are in a 96 by 36 tank right? Reason I ask is I was going to buy from BRS (can't decide the type yet but leaning toward Reef Saver because it seems to lock together better (?). Anyway I don't want to overbuy but want to get it early enough to cure it. They were saying 400lbs but that seems high to me and given what you've got...
I think you need to remove some rock!
I agree! I found myself putting more in just for the sake not wasting it.
