So I have about a 2 lb piece of LR that I took out of my tank because it wad covered in that razor algae and I didn't want it spreading all over my tank. Now that it is completely dry and dead is it safe to put back in my tank? I could rinse it well but will there still be a lot of die off? Possibly an ammonia spike? Its still got a little bit of color from the coraline algae on it. What can I do to make it safe to put in my tank? Here's a pic of it now.
