I was just thinking about it. Would there be any Benifit to once a year or so add a small piece of live rock to the sump? Not the live rock you find in the bins at the LFS but the stuff that’s farmed in the gulf with lots of growth on it. My LFS calls it premium live rock. Something to keep the biodiversity fresh. Or are there any products similar to the pod cultures you can add to keep your pod population fresh?
