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.
Overall, a good guid to giving a salt dip, but ther'e many problems with this also. 30 to 50 years ago, salt was the only readily available medication and therefore salt was the way to go. However, nowadays this can greatly harm your betta. It is a myth that salt is the cure all first line of defense for everything. bettas have a very low tolerbility to salt and it greatly decreases their immune systems. I also want to point out that there is a difference between salt dips and baths. While many use these terms interchangably, it's still wrong and can be confusing. Your describing a salt dip in this paper. Now, i only graded you on the info you provided, but i would of also liked to of seen what salt is doing to your fish and how it's helping. this might of also helped you see my salt is a danger to fish and what you can do to avoid these problems.
