So what to put in the sump? I have the return pump for the left side. For the right i have the overflow pipe and a carbon bag. And the center will be the refugium? But what do i put in the refugium, sand, live rock? not 100% sure.
Live rock questions? Ok lets say i get 10lbs of live rock for my 55 gallon tank, lets say i put base rock in for the rest of the 40lbs will that work? also do i need to put live sand if i have live rock? i was thinking about a 2 inch sand bed of just regular sand i think that will be deep enough maybe 3?
So any feedback would be much appreciated.
