  1. Default Should I use existing filter in new tank?

    I have a biological filtration filter in my old tank but, still have a betta fish in there. So should I put 1 old filter and 1 new filter in my new tanks filter cartridge?

    You are upgrading your filter?

    Yes, you can put existing filter media into your new filter to "seed" the new media with beneficial bacteria. The betta will continue to provide ammonia to "feed" the existing bacteria and help grow new stuff in your new filter.

    No, I got a new tank with new filter and cartridge.

    So, you want to run your new filter on the new tank and put a cartridge from your existing tank in the new filter - what will you use for ammonia to "feed" the existing bacteria and grow new ones? You are doing a fishless cycle I assume.

    Yes, I'm doing a fishless cycle with pure ammonia.

    Alright, we are going to need more information from you to give a proper answer. What exactly are you trying to do?
    Upgrade your betta tank and the betta will move to the new tank?
    You have a new tank but the betta will stay in his old tank?
    The better answer to your question depends on the answer to my questions.
    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.
    Imitation is the sincerest form of flattery.
    Dear naps, sorry I hated you so much when I was a child... Love me

    If you are starting a new tank and the old tank has approximately the same bioload as you plan to put in the new tank, you don't need to cycle the new tank at all. Its an instant cycle. Size of the tank doesn't much matter, its bioload.

    How much seeded material (filter media, sand/gravel/deocrations) you can move from your old tank to the new directly affects how much fish you can stock at once. If you have a single betta in your old tank, then you could stock a single betta in a new tank with that media moved to the new tank, and not worry about ammonia poisoning.
    If your old tank had 20 guppies in it, and you moved the filter and some gravel from that tank to a new bigger tank, you could start with 20 guppies or the equivalent, and not worry about cycling, so long as you transferred enough seeded media over.
