I think this is a good article, but I would like to just point out a few things. When regarding dropsy you'll need to be doing 2-3 times a day to help with the treatment, so the "only five times a week" statement is good for just. bloating and such, but shouldn't be applied to dropsy. Same with the no epsom salt in the tank, you'll need that in the tank when you are treating for drops. Granted it is significantly less than the amount used in baths (1tsp per 5 gallons). I also do not see the amount of salt needed to be used in this article? Overall this is a good article, but I think a few touch ups could be added to make it even better.
