This may be a very stupid question, but what do you guys use to wash you fish-dishes? We feed the LRS Reef Frenzy Nano, but the pieces of meat are still too large for the tiny mouths of the firefish we have, so I end up having to mince the frozen chunks before they're thawed. Nearly everything I've read says not to use soaps or detergents when cleaning things in and around the tank, but not doing so for the knife and cutting board that comes into contact with raw seafood daily is just a biohazard. I'd prefer not to poison the fish with trace elements of dish soap, but we don't have a dishwasher to even do just a hot water cycle. What do you guys use? "Reef-safe" soap brand recommendations are welcome as well!
