My betta died. but I am looking to clear the tank of all parasites! I thew out the gravel but couldn't part with the plants.. I put a lot of hot water in and then have been dissolving A LOT of salt. more than a fish could survive in. I don't have an exact measurement since I was on a vendetta...

my female betta has had fin rot for so long and i cant seem to fix it and it is starting to get worse! idk if its because she swims so much or if it is getting torn on something, if you know what i can do to cure it, please respond to my thread.:-( here is a pic
