So, I had a 20 gallon tank until a recent non-water based disaster. When I shut it down, I kept about... 5lbs of LR. The tank had 42lbs of LR. So i have 37lbs of LR that has been sitting out and either drying off or otherwise not being submerged in water. I dunno if it's still damp enough to be "live" rock, but I do know that it's probably filled with dead critters. I want to know the best way to get them out of my LR without destroying the LR. I don't have any money to spend on new LR, so I do want to recycle the old stuff. So, how do I sterilize my LR and render it dead rock?
