live rock in sump/refugium... Why?

There should be more than enough flow in the display to allow live rock to filter to its full potential. If that is an issue you need to add more flow in the DT, not rock in the sump.

One thing that many people forget is to get enough flow BEHIND the rock. The only pump I had in my DT was blasting water behind my rockwork. This flow gets water moving all around and through the rockwork which allows it to filter better.

I would only worry about rock in the sump if you have filled up your DT and still have more rock.

I have lots of flow. Have 3 power heads totalling over 2000 gph, not to mention the flw to/from my sump at 450 gph.

I do not have any rock touching the glass for cleaning ease. But i have about 100-150 lbs of rock in my 90 gallon.
