Default Re: Cycling A New Tank

I only setup my new 10 gal. tank on Sat. I put the old filter in from my 28 gal tank. added some gravel a heater. I plan on adding a bit more gravel. When I tested it today the Ammonia was 0, Nitrate 0, Nitrite 0, I have never had these readings in my 28 gal tank. Is it ready or is this just the calm before the storm. I am not adding any fish till I have the tank decorated the way I want, but is it possible for a tank to cycle this quick.

I have had tanks cycle right away with just using water from another tank. I did dig down and get some of the "good stuff" out of the gravel to go along with the water. I never did get an ammonia spike with my 29 gallon and so far, I haven't gotten one with my six gallon either. My readings always stayed where they should be. Weird.

If I were you, though, I would wait a bit yet just to be sure. You had such a pain with the first tank it would be a shame to go through the same thing with this tank.

If there never was an ammonia reading, the cycle probally never got started. Adding bacteria without an ammonia source will not cycle a tank. The bacteria need ammonia to grow.

I agree with Dano! If you are doing the fishless cycling Sandy, are you adding fish food to the tank? the decaying food produces the ammonia needed.

In any tank when it has cycled you should always have some reading of nitrates.

Sandy, you CAN use household Ammonia to cycle, or to see if the tank is cycled due to using a mature filter. Add just enough Ammonia to get a reading of 5ppm(you won't need much to do this). Wait 24 hours ....if the readings return to 0, the tank is cycled. The Nitrates are probably reading 0ppm, due to having all new water.
