Hi Fishyfriendzz. Having done this unintentionally once, I can tell you there is only one thing that's guaranteed: trouble. Too many variables. The timeline and the volume/frequency of water changes will depend on the volume of the tank, filter and substrate, temperature, water hardness and your bioload. If this is absolutely necessary, you may use Prime to help handling spikes, but nitrite spike may happen suddenly and quickly kill your fish overnight or when you are at work. Have you got anywhere to seed your filter from? Friend's tank or LFS? Seeding will speed things up.
Anyway, if you have a choice don't do fish in cycle.
And yes, the water will get foggy and there will be yucky slime and what not during cycling, fish or no fish. Read about nitrogen cycle and fishless cycling. This forum has enormous archive, very useful.
