stir it up? When I use the turkey baster to blow the rock off and stuff is that bad? I try to do that right before I suck everything out for a water change.
blowing the LR off and stirring up the substrate are 2 different things. If you stir up the substrate to much you risk releasing the nasty stuff into the water column.
Thats kinda thing, I would like to stabilize my LR with pvc due to my engineer on crack cocaine and digging up the entire tank. I would be stirring up the LS a little pushing the sand back and leveling it out.
