    Hi all,
    How do you allow a tank to cycle?

    When i last did a water change, the first one for my guppy tank, i add bactozym to mature my fluval one plus, and add aqua safe and easy balence.

    y other two tanks are fine as theyve bin running for ages, this guppy tank has been running for a couple of weeks. im getting fry, but the water quality isa bit poor.

    Can any one help?

    Your guppy tank is trying to cycle with the fish in it. It's generally not a good idea to cycle a tank with fish because the high levels of ammonia & nitrIte can kill them, but since you already have the fish, just keep doing water changes and try to keep the ammonia & nitrIte as close to 0 as you can.

    You can also take some of the filter media from the established tank and put that in the filter on our guppy tank. That will transfer a bunch of the beneficial bacteria to the guppy tank and the tank should cycle pretty quickly.

    thats great advise, but my guppy tank has a box filter, and a fluval one plus. My establsihed tank is a jewe reckord 70 so the filter media is bigger than the fluval filter, and my cold water tank is a fluval 2 plus, so again the media is too big.

    what options have i left now, just the water changes?
    do i have to stir up the gravel?

    The media doesn't have to fit perfectly. Just cut off a chunk and put it in the new filter. As long as there's water flowing over it, it should be fine.

    i cant do that im afraid,

    The juwel filter is designed with the media to fit and if i remove bits it wiont be effective, and the fluval filter pieces are needed coz of the amount of waste produced by the cold water fish.

    Just smear some of the gunk from one media to the other or transfer some of the gravel from the established tank to the new one.
