I know this has been asked many times but, I feel the need to ask as the other posts don't answer my questions.
Here's the story... My betta Lucky died last night from some unknown cause. His only symptoms was being lethargic, loss of color and gasping for breath. He died only one day after showing these symptoms. I did what I could but it was to late. He died in a QT tank.
Now that he is buried I would like to thoroughly sanitize his tank for a new fish. I plan to throw out the gravel but I can not throw out any of the decor, heater or the tank it self.
I have had one person suggest using vinegar, how would one go about using vinegar to clean a tank? I have also heard about just rinsing the tank in hot water and leaving out side to sun dry. If my betta died from somthing contagious I definitely don't want my new Betta to get it and die also.
How would you go about cleaning the tank, decorations and heater?
Thanks in advance!
