Hi Gazza
I think the static idea could be the right way its probably the best for sediment traping, all I have at the moment gaz is a 4ft dia. by 5ft deep vortex on both systems followed by the 4X3X4ft deep bays full of brushes. These are infact spawning brushes bundled in and they do a good job but need regular attention and that is what I need to improve on.
I also use ladys tights (keep it to yourself) cut of at the crutch

and one leg placed over each of my 6in. transfer ports from my vortices
they work well but again they are heavy maintanence.
There is also the filter box on the skimer with brushes and foam.
Oh and thanks for the link eventualy
this is the bay after fitting the deflector screens
vortex
no prob. with questions bud ask away nice that you care
