Craig that is why I started my post by saying that you have to look at the system as a whole,and not individual parts. As you mentioned thier are different over all concepts, but I do believe that each system has to be taken as the whole.
In your case you probibly cant have the same kind of flow as me, and cant have it directed to the bottom of the tank, You DSB is going to sink and cycle material that cannot be removed through this flow pattern. In you case and as a total system Water changes are very needed.
In the different ways of doing a reef this is true and not true. The biology behind the tank will never change no matter what you are trying to do. What we can do is to is create a series of checks and balances to make up for short comings. These checks and balances alway come with more check and more balances, This is where we really need to watch how difficult we make our sytems. A system that relies on to many checks is like a house of cards, alot of times if you follow members trials and tibulations you can see them go from problem to another, this is usually a result of to many checks.
