What most breeders and people with fishrooms have is something called a drip system. You can see it in those pictures but this video series
(the link is for part 1 of three) might help you out a little more. =] It's not as detailed as it should be but it's a basic guideline that it might help you to follow. Of course you can customize it to your needs and tanks and this is where the research comes in. =]
What makes these systems awesome is the one main filter. It cuts down on cords and individual maintenance.
You'll also want to PM some of the breeders on this forum and possibly a member whose username is Chrissy. =] Most breeders have a drip system of some sort in use. even if it's not for the fry.
This is a big undertaking. What's your time table like? When are you planning on starting your project? =]
