which do you think is better the plastic bio balls or ceramic rings, and why?
Zagz said:I personally think the ceramic rings are better as they are porous and the bacteria sticks in the holes more than with bio balls. I use both but when I rinse the bio balls they come much cleaner than the rings proving to me that they bacteria doesn't stick as well to the plastic.
