help with fin rot

[moose]

about a week ago i noticed that my male bettas tail started to get fin rot. so i did some research and i read that using aquarium salt and keeping the water clean will help to get rid of it. so i've been cleaning his bowl everyday for the past 5 days and putting 1 1/2 teaspoons of dissolved aquarium salt in the water. but it seems like its just getting worse. the rips in his fins got longer, but the black seems to be going away. should i wait longer and continue with the aquarium salt or should i get some medicine from the pet store? He lives in a 1 gallon bowl at the moment because i want to get rid of his fin rot before i put him in the 10 gallon tank i have.
the water in his bowl is heated to 78-80 degrees fahrenheit. he swims,acts, and eats normally. some advice would be very appreciated :)

In my experience keeping a betta's fins are next to impossible in a 1 gallon. Even with twice weekly water changes and a 100% at week's end they all end up with fin rot..

2 gallons is very minimum for keeping bettas and then you need twice weekly.

How are his fins now?

yes i know a 1 gallon bowl is too small. that's why i can't wait for his fin rot to clear up so that i can put him in the 10 gallon tank that i got from my sister. do you think putting him in the 10 gallon tank would help him get rid of it faster or should i just keep him in the 1 gallon bowl and do 100% water changes every day until the fin rot clears up? his fins right now, after 10 days of treatment look like they are improving but i'm not really sure. there is still some black parts but the rips don't seem as bad

You could fill the 10g half full (5 gallons) and treat there by doing 50% changes every other day and 100% chanfe once a week. That might be a lot less stressful on him and easier for you. You don't even need to put gravel in there but he will need a heater and in my experience a little air stone under the heater or you will have hot/cold spots in something that big. Also some plants and places to hide.

Ok, i'll set up the tank and put him in it with everything he needs. I don't have an air stone though so i'll see if i can get one. Thank you for your help
