Hey guys ok I just got a 10 gallon tank I already have a fully cycled 10 and 20 gallon tank and I put the media from the new tank in my 20 gallon and I wanted to know how long do I let it sit in there

If you just transferred the cycled media then thats it. Presto, instant cycle. Just make sure theres an ammonia source in the new tank within a day or two.

Edit: I seem to have read that wrongly. Yes, mommy1 is correct.

It will take 3-4 weeks for the new filter to cycle on the old tank.

Note On Cycling: Set up the tank as instructed. However, before you add the fish, you must run the filters for a few weeks to let the tank settle and let the bacteria in the tank to adjust so the tank will be healthy for the fish. You should to let it cycle about a month.

As for power filers for a goldfish tank, I recommend a good canister. setup. It is costly to setup at the start, but a good canister and a hang-on the back power filter to act as a skimmer will keep a goldfish tank running well, and help keep the fish healthy.

Remember, goldfish grow fast and big. so if you can afford to buy a 55-gal tank setup, you're have good place for 3-5 goldfish. This is only a suggestion.

Just to clarify - this will only work if you are feeding your tank pure ammonia. A tank simply running with a filter will NOT grow bacteria that is beneficial to a cycle - no matter how long you run it. see the beginners section on fishless cycling for full explanation.
