I will be moving soon, I'm trying to figure out the logistics of moving my tanks and fish. I have a galvanized water trough used for livestock, about 100g. Would this be okay for temporarily holding my fish? I'm thinking they would be in it about 2 - 3 days while I move the tanks, reheat them and acclimate the fish to the different water. My concern with the galvanized trough is that there may be something harmful in the galvanizing that could leach into the water. The trough was used for my horses for a few years so maybe anything harmful has already leached out? Any thoughts?
