I have a used reactor that I bought which had been a CA reactor, and it's full of coarse media. I'm going to turn the reactor into a sulfur denitrator, and I'd like to keep the media for when I finish my CA reactor. I don't know its age or anything, but I'd like to put it away for later.
What's the best action? Freshwater rinse? Bleach/sterilize?
