Good question. Id like know as well. What diseases can be carried by inanimate objects? Which ones have to remain in saltwater in order to stay alive? Finally, what is the best method to terminally clean aquariums and all the accessories? You’d think bleach would take care of it. But even with that, Ive heard of ciliates or brine shrimp eggs remaining viable. No kidding. I do believe that about the brine shrimp for sure and I’ve had ciliates pop up randomly in new rotifer cultures. Suspicious.
