the one thing that i will caution you on is how wide the baffels are... i just recently built my first sump, and there are a couple things that i would definatelychange..
i'm flowing roughly 600-650 gal per hour through mine, and my baffels are 2 inches apart, its not far enough to let all the bubles work thier way out. the smaller bubbles get cought in the flow and make it all the way through, defeating the baffels...
so, you might want to think about what flow, and i mean true flow, not theoretical maximums, and then adjust the spacing on the baffels to match, cause if i had mine to do over, i'da gone 3 inches wide, for a couple reasons, one i have thick forearms, and at 2 inches, i cant reach down between the baffels if something falls in there, and 2 the flow and bubble issues...
i know it takes up more length in the sump, but it'll work better and you'll be happier, and not have to be re-working what you've already done.
oh, and i noticed that you are planning a 2 baf system rather than a 3 baf system, just my personal preference, but i think that the 3 baf is a better way to eleminate the bubbles...
the math looks a little like this(im rusty so cut me some slack)
i have 600g/h flowing through a "pipe" with dimentions of 12x2 or a cross sectional area of 24 square inches, so,
600g/h/24sq-in=25g/h/sq-in.
so, when you figure your math, i would suggest getting your flow per hour per square inch below 25, what it should be i dont know, but i know it needs to be less than 25 for all the microbubbles to be able to get out....
anyone know more about the math and physics of entrained air bubbles in a flowing water system?
its just been so long since i actually sat down and thought about all that stuff that i think i may have forgotten a bunch of it...
