Sump ideas for my RSM250

[spawn]

Here is a couple of shots of my tank this morn. again this is my first saltwater setup & it is 6 Months old started on May 9 2010. I think things are going pretty good so far. I run an ozmolator, 1 Koralia 3, 1 Koralia 4, 1 ecotech voretech Mp10w, & the 2 stock pumps with the stock skimmer. Parameters
Sal. 1.026
Ca 420
Mg. 1300-1350
No 3 5-10 ppm & dropping

Sorry about the shyte picture quality. I can't figure out how to get a decent pic. with my camera. It's an Olympus Stylus Tough & IMO the worst P.O.S. camera I have ever had. But you can take it diving to 33ft.
