biological filter designs

[deank]

Hi, I wish to set up a marine tank in the near future and would like to save a bit of money building my own filtration system, I have a spare 2ft tank that i would like to use without having to drill, My problem is that I cannot seem to find any good diagrams on how to do this, where do the baffles go what media goes where etc, this may sound simple to a lot of people but being a newbie well that speaks for itself.
The size tank I would like to setup would be approx 4ft x 2ft x 2ft light is another issue but I have time and would like to try the filtration first.
Thanks heaps in advance.

Here is a link: http://www.ozreef.org/diy/index.html#SUMP

In terms of filtration, all you really need is a deep sand bed (aragonite, lots of live rock, and a good skimmer.
But you can build a sump for better water movement and distribution and to hide your equipment.

dattack pretty well said it. A DSB and macro algae will handle most anything.
