So today i had to euthanize one of my bettas
Now i have a extra 5 gallon tank....i want to sanitize it because he died of a fungus infection.....how would i go about doing that with out leaving any chemicals behind in the gravel????? I also have a bio-wheel on the tank, will it carry the fungus???? If so how do i treat it with out harming the helpful bacteria???
Thanks for your help
