I have aprox 500 extra bio balls, loaded with good bacteria, that I am going to move from one tank to a newer tank. I was considering putting them in the sump area of my wet/dry filter. I have a heater in the sump portion of the wet/dry filter. I am wondering, what happens if the bio balls come into contact with the heater. Any kind of issues there? Does the heater get hot enough to melt, or cause some other issue with the bio balls. I know they will float, but there are so many, some will be forced downward toward the bottom of the sump. Thanks for the info
