So I have a new tank in the works, got a used skimmer and bio reactor with wet media still inside. How do I clean them, and should I worry about any diseases being trapped in the wet media? It will be much longer than three months by the time they are online, so if there was a disease, it should have died off by than right? In the bio reactor there is a bit of vinegar left over from him cleaning it, to get that out should I just run some RODI through it, not looped so that the output just runs out, clearing excess vinegar?
