Sump Baffles

[Captainhemo]

Is it better to have the water leave from the bottom of the skimmer (1st) chamer then go over and back under ( the middle baffle would determine the depth of the water in the skimmer chamber OR have the skimmer chamber sealed at the bottom and have the water go over /under /over withthe 1st baffle determining the depth of water in the skimmer chamber ?
I would think the skimmer would tend to skim the smae water if the chamber was sealed at the bottom and the water flowed over the 1st baffle. However if it goes under, whats to stop all the "crap" from just flowing through/
What's the better way to go ?
