:( Poor Lando. I've never gone past 3 tsps but DarkMoon recommended it once for another really sick fish. I don't think it could hurt him to try 4 tsps but if you see him start to twitch or react to the higher levels, move him back down to 3tsps immediately. Let me know how it goes.
Hey sorry I fell off the earth for a bit. :( Lando is sadly sick again. Eating well but bloated with what everyone thinks is worms. Have you ever moved a fish past 3 tsp per gal of epsom salt. I'm starting to think that will help him a bit. What do you think?
