New tank set up with 'old' gravel

    when we get our 90g tank, and we use the gravel from the 26 and the 10, along with the fake plants and decorations will that give us a good start on the bio filtration? do we put the old gravel in first or on top?
    will that be a big enough load to start to cycle the tank or will we need to supplement with bottled bacteria of some sort?

    Hello k9z3boys, your decor and gravel will have some bacteria and will help with cycling the tank, but wont speed up the process too much as the bacteria colonies that live in your filter media are what oxidize ammonia and nitrite the most. I suggest you take the filter media from your old filters and place it in your new tanks filters to speed up your cycle. Also, i've moved your thread to the aquarium nitrogen cycle section of the forum. Best of luck.
