    the filter? you mean the filter pad? what brand and model is your filter?

    If you are just needing to replace the filter cartridge because it is worn out and if there is room in your filter housing just run both the old cartridge and the new cartridge. If the water no longer flows freely through the cartridge or there is not room to run both of them cut the fiber off the old one and put that fiber in the housing along with the new one. This way you will not be throwing away the bacteria that is keeping your tank cycled.

    The obvious question is what kind of filter are we talking about?

    I am changing the whole filter, new system. i am going from a aqua tech 5-15 to an aqueon 20 because i accidentally bought the wrong size for my 25 gallon so i am putting the aqueon on my 10 and giving the aqua tech to a friend. I am just wondering how i should change out the filters because i know that will mess up the nitrogen cycle

    if the current media in whatever filter is on the tank is cycled, take that out and put it in the new one.

    The only problem is that the filter cartridge is way to small for the new filter

    Uae that cartidge to seed the other one. If theres room, tuck the old one behind the new one or consider placing tye old one near the filter intake. Just leave it in there for a couple a weeks, and then take it out.

    Okay so i should use the full cartridge or just pull off the front piece?
  11. Mike1995Well Known MemberMember

    if there's room, I'd use all of it. bit if needed, just take off the front.
