i didnt have a cycle in mine. i left it a week before anything went in
Ah ha - interesting
Wait for the nitrite to disappear and then big water change

If your Nitrates are at 100 you are still cycling or there is an issue somewhere
Did you buy your LR from a LFS or second hand?
How much flow have you got in the tank ?
Morri, that is his Nitrate spike
Excellent, so water change has now been done and all params are as to be expected - test again in 24 hrs and lets see if they hold steady

100 is very high for a spike but I guess this is down to a lack of flow adding the powerheads is essential before adding anything to the system as there will be dead spots which will be exposed to flow once the power heads are started and could mini cycle again.
So what are the readings? Remember, in the cycle, its ammonia, nitrite and then nitrate (not the other way round). It looks to me as though you are having a mini cycle, but lets see the results that you talked about
