    The carbon is not needed but if you choose to use it, it should be replaced every three to four weeks. The bio-max and sponge don't ever need replacing, just rinse the sponge off once in a while and reuse.
    When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top... Kingfisher
    Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.

    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.

    Dear naps, sorry I hated you so much when I was a child... Love me

    The only reason that manufactures recommend replacing the bio media and the sponge after a certain time is to make additional money. The carbon is not really useful in a well maintained tank and you should save it for when removing medications/ other emergencies and get an additional sponge or bio media pack to replace it.

    I agree with the others. I have a couple of aquaclears that have been running since 2007 with the original sponges and biomax. I don't use carbon.

    i hear some people say, "i kept a goldfish in a bowl and it lived for a year."
    they don't know how lucky they were and all goldfish live at least 15 years in proper conditions.
    that is equal to saying my human lived in his closet for 5 years!

    Awesome, thank you. I have an extra sponge and bio-media. Which should I use in place of the carbon?

    Biomedia - the more room there is for bacteria to grow, the better - just make sure that you periodically clean whatever is in there for mechanical filtration (like squeeze out the existing sponge in tank water) so it doesn't clog up with larger particles.

    My one piece of advice is to change the sponge every once and a while. I know it gets rid of all the beneficial bacteria in it every time you do it, but I've noticed that the sponges start to break down after a certain amount of time. Since I'm not sure if they leach dangerous chemicals and I don't wanna take any chances, I replace it when it gets like that. If you have established bacteria colonies everywhere else, changing the sponge every so often won't hurt (at least I've never had any problems with it).
