I would never get rid of my DSB in my display. its 330 lbs of Southdown that averages 5" deep in a 100G tank. My nitrates are undetectable and overall water quality is great. No sandstorms and I have 2 Sicce Voyager 3 powerheads (just replaced 2 K4 Koralias) on a wavemaker, a OR3500 closed loop pump thru a OM Squirt two way and a OR3500 return pump so lots and lots of random flow.
I have had both ways and even bare bottom and much prefer the DSB.
