disinfect tank

    Do you need to disinfect tank that held sick fish?

    A fish with dropsy died in my 20 gallon tank about 6 months to a year ago. I emptied the tank right after the fish's death. The tank's been sitting in my garage and has dried up a long time ago. Do I need to disinfect the sand and tank to use right now? If so, how would I disinfect the sand?
