So currently i personally have maybe 400 lbs of rock and a 330 DT with a 220 sump. My current setup has most the rock in the DT but want to move some more to the sump to keep the DT cleaner and more open space for the fish to get around. I have seen some of the build threads utilize some of the big 150+ gallon containers filled with rock on top of the refugium and DT. So this is mostly aimed to them... Do you guys see a noticeable difference with a massive amount of rock compared to just the standard recommendation of 1 : 1?
