How to cure Finrot?
Day 1 - do an immediate 40% water change and examine all aquarium conditions. You will want to follow the 6-day treatment to cure this disease.
Premix these ingredients before adding to the main tank:
Salt: 1 tablespoon per 10 gallons(aquarium salt, kosher salt, pure rock salt or sea salt)
Epson salt: 1 teaspoon per 10 gallons
Melafix: 1/2 teaspoon per 10 gallons if pH not over 7.5
Combine salts into 1/4 cup of warm water to dissolve. Mix to dilute Melafix in a freshwater Bucket.
! Replace only 5%(of fresh water) every 15 minutes to reduce the risk of shock. Add water treatment to the water you add to the tank to remove ammonia and chlorine.
Day 2 to 5 - you will repeat the following process:
- perform a 20% partial water change using the directions on 1st day
- add salt: 1 tablespoon per 10 gallons
