I've recently purchased a Fluval Chi 5 gallon tank. Not my first fish tank, but first after reading everything on here. The filtration set up pulls water first through a white filter with carbon in it, to a fairly open sponge type media (less dense than steel wool is the best description I can giv). If I change the white filter, will my beneficial bacteria live on in the sponge area?
