Thanks!
I think that the height variation creates a lot of movement in the layout.
Plus, it allows me to put corals in diferent heights, according to their need of light.
My sump/equipment didn't change. My skimmer and my Ca reactor are both great pieces (SRO5000 INT and SRO CR5000 Dual Chamber).
I still have 2 150 TFL reactors running empty. From time to time I put a little GAC and remove it after a week.
The chaetos was removed almost entirelly. I left a small portion in the frag tank....just in case.

My sump still looks like this:

From the start I've changed my Lighting and now I run 5 AI (3HYDRAS52+2VEGAS) over the Big Island and 3 AI(2VEGAS+1HYDRA52) over the Small Island.
I also improved my circulation and now I run 2 Gyres 250 + 2 Icecaps 3k, along my MP40.
