Deb, the rock was acting as a sink for the detritus, and I feel that the remaining rock is more than ample for filtration. I do also have about 1.5 inches of sugar sand on one side of the tank, so that may or may not contribute.
Right now, I have more than a pound of LR per gallon. If I get to the point where I don't have enough rock for filtration, I'll make up for it with water changes.
