So I've had my saltwater mixing bin sitting around for a couple days with an electric thermometer and power head in it. I didn't realize that my thermometer display dropped into the water and now when I took it out I can see corrosion where the battery compartment is. I'm thinking the water is no longer any good but I wanted other opinions about it. Dumb question, just want to make sure the water is no good and I would have to replace it. Thanks!
