That nasty stuff you see on the cartridge, it may be the bacteria you want to have in the tank. The reason why its not a good idea to replace those cartridges is because the beneficial bacteria will colonize the filter pad and in any decor in the tank. Most of it will be in the filter though. It's better to just swish the cartridge around in old tank water when you do the water change then it is to replace the entire cartridge (and its why I use the aquaclear foam - it lasts ALOT longer). Everytime you replace a cartridge you are tossing out the bacteria you want to keep. The carbon, however will only work for about a month.
i think though i would rather have the carbon that to have nothing? your basically just using the sponge with no carbon? would that mean my filter is doing a better job than your one coz i have the benefit of the carbon?
could you possibly link me a link to the sponges u buy please, because the one that came with my filter they have a plastic frame that the pad is atatched to and this frame slides into the filter box, without this frame i dont think a loose sponge wouldfit in place or even stay in place..
one thing i was thinking of doing was just buying another sponge and wedging it into the filter someplace and elaving that in there along with the one thats allready in there with the carbin it it,that way when im changing the carbon filled pad for a new one ill still have a piece of sponge in there with some bacteria on it..
i was also thinking another option, when i am taking out the old sponge to replace with a new one,i could cut off some of the old sponge and just put it into the filter with the new one for a week or so untill the new filter gets the bacteria on it,then ill throw out the piece of old sponge
is any of this a good idea?
