when bacteria die off on the bio-wheel, do they stay on the bio-wheel or disappear with time?
i'm asking because if they remain on the bio-wheel after dying, they are taking up space where other beneficial bacteria can grow, limiting the amount of bacteria that can colonize.
this is the only other reason i can think of for my bio-spira having so little effect on eliminating the mini-cycle, other than that it was shipped improperly.
also, there's brownish muck on the edges of the bio-wheel. is this beneficial bacteria?
