First-off, well done mojo/poo/Mike
Also called the Monaco-style system becausze of its use (and success) in the Monaco aquarium.
Here is a link to more specific information about the Monaco system
This is similar to the system I run in my tank and it seems to be just as effective as a DSB, although I question whether it is
more effective. I think substrate size is crucial and I don't have that nailed down at this point. FWIW, I also run with a skimmer and a fuge so it is incorrect for me to say that I run a Jaubert or a Monaco system, just that I have a plenum.
Anyway, I forgot what else I was going to say so good work Mike!
Take er easy
