Re: tank not cycling?

Cycling a tank just requires an ammonia source which means that you could just throw a prawn in and wait for it to begin to decay because ammonia is released when the prawn decays?
I have a tank cycling at the moment - I have used the water and media from an existing tank and i've thrown in a frozen food cube for good measure. It's been cycling for 2 weeks and the ammonia has fallen to about 0.3 and the nitrite is between 2 and 4, I haven't checked the nitrate yet because I don't see the point in checking until the nitrite begins to reduce.
The trick is to monitor the ammonia level once it has begun to fall and keep it at about 0.1 (by adding additional sources) until the nitrite reduces, then do a large water change, check your parameters and depending on the results add fish - it worked for my last tank!
It sounds like your bacteria is producing nitrates and is therefore on the way to cycling, i would suggest that if there isn't any animal life in your tank at the moment then you should try adding more ammonia (in a larger dose) which will therefore feed the ammonia consuming bacteria which will produce more food for the nitrite consuming bacteria which will produce nitrate.
Just keep in mind that ammonia and nitrite are food for bacteria and they are not bad things until the animal life is added. If one of the food sources is reduced to zero then the bacteria will starve and die.
