Tropical tank cycle help

[tropicalfish1]

it is possible to cycle a tank in two days?

I have had my tank running for two days with filter on and heater on around 30c.
I have added nutrafin cycle
Also fish flakes every 12 hours
I have added gravel and ornaments and filter media(which was covered in bacteria) from an established tank that is cycled
After just over 48 hours of the tank running i tested the tank these were the results:
Ammonia: 0
Nitrite: 0
Nitrate: around 60!!
pH: around 7.5

What should I do now? do a huge water change and add 1 or 2 hardy fish? i find it hard to believe a tank could have cycled in two days

To cycle a tank is to allow beneficial bacteria to grow which break down ammonia to nitrite and nitrate. It takes time for ammonia to accumulate especially with no fish in the tank.

To test you need to add an ammonia source to feed the bacteria. Fish food wouldn't be enough to add any significant amount of ammonia. When the tank can process 3-4 ppms of ammonia in 24 hours and the tank stays at 0 nitrite and nitrates rise then you're good to go. http://www.aquariumadvice.com/forum...guide-and-faq-to-fishless-cycling-148283.html

If you are adding significant amounts of seeded media I would consider the tank pretty much cycled. IMO you can go ahead and add a couple of fish but you will need to watch the parameters closely.
