Well, I put two teaspoons of salt into the tank just now. One of my neon tetras has not been doing good for the longest time. I put it in a bucket on the floor and covered it with a blanket so it was out of the light. I put it back in the main tank when I turned the plant light off. I figure the salt might help it recover a little and help the rest of the fish out as well. I've got the testing kit ordered, but it could take a week before I get it...
