    That's right, i'm asking a cycling question.

    Will my new 20 gallon long cycle quicker if I use 50% of water from my 30 gallon tank?

    What in the water is beneficial?

    It will help some, but it would be better if you take a large rock or piece of deco and put in the new tank, that should have a lot of beneficial bacteria. What I do is use 50%-100% old substrate for smaller tanks.

    It won't hurt anything but you would get more benefit if you threw a handful of gravel in the tank, or any other hard object from your cycled tank.

    Nearly all of my tank have gravel from other established tanks.

    If you use enough of it from a well established tank it is probably about as good as a chunk of filter sponge at jump starting a cycle. If the gravel doesn't happen to match the new decor you can throw it in a media bag, nylon stocking or whatever.

    Don't use gravel. I use black sand. But I do have 4 rocks in tank. 3 Quartz Rock and 1 regular, I found all in the garden bed outside of the apartments we live in. (Don't tell the Manager!).

    Use the rocks, They will help. I hate buying beneficial bacteria, when you use your own for cheap.

    Does your filter have another sponge or bio rings that you can throw into the new tank. Typically I keep like an extra bag of bio-rings or sponges in my filters so I can start a new tank or a QT on the fly w/o having to wait for a tank to do the cycle.

    If you don't I would put an extra bag of media or sponges in the filter and let that soak for a few weeks and you'll cycle your tank quicker.

    I only have the filter sponge currently in use. But I do have filter cartridges I can use.

    Yeah drop whatever media be it sponge or rings into the filter if you have the room. Leave it there for a few weeks to a month and you should be able to transfer it to the new tank.
