i have my baffles 1.5 inches apart w/ the floss - the bottom between the two. i decided to use only two baffles due to the small size of my sump and i needed space for my protein skimmer. the first baffle is 10 inches high, and the second is about two inches off the bottom and one inch above the other baffle. sorry i have no pictures at this time i'll try to post some later. thanks for the reply!
