Sump baffle height

[Safedad]

I am adding a sump using my old 29g tank. I will use 1/4" glass baffles. What height should the final baffle be relative to the one before it? Assuming I have calculated the right return capacity if the power goes off, suction is interrupted, etc. what difference does it make regarding the height? I have added a word attachment of my ppt drawing.
thanks

I have updated the plumbing in the drawing. Since this is my first, I would appreciate any suggestions. After I get this down pat, I will work on my plans for the overflow to supply the return lines. Hope to add SCWD in Aquarium supply.
Thanks

whatever the heigth of the last baffle will be the water line for your fuge section so keep this in mind.

Dave, Right! I am assumming taller is better, provides most options later on. I will go with 14" then. I calculate that I have 1.6 gallons for every inch of the tank- (30X12X1)/231. At 14" the sump could hold between 4.8 gal and 6.4 gal of backflow when I shut off the pump.
Thanks for the comment
