    Hello! :;hi1 I was wondering what you replace/change when you are servicing your filter. Do you change the whole cartridge thing or do you just change the carbon? Do you change the sponge part rather than the carbon? I was just curious and I don't want to put my tank into a mini cycle when the time comes. :;thx

    the idea is that the sponge is what holds the bacteria so never change it.

    So you can change the cartridges but not the sponge?

    The coarsest material, (usually sponge) should never really be replaced. Simply rinsed out in old tank water, (never tap water). Carbon should be replaced every 3-6 weeks depending on quality & the amount of 'contaminants' it has to remove from the water. Fine filter material like floss can be rinsed out or replaced.

    I hope that helps.

    Of course, its always a good idea to stuff the filter chock-full with filter floss in case of a mini-cycle.

    I replaced all the pads, charcoal and such with sponges many years ago. I rinse them out in used tank water and put them back in. Very economical and they will hold lots of beneficial bacteria.

    Okay, thanks! I don't want to ever have to put my tank into a mini-cycle, so now I know what I should and shouldn't replace. :) Thanks!
