Is there such thing as too much ammonia for cycle?

[ps2cho]

So I threw in about 2oz of white fish that was sitting in the freezer far too long and I didn't want to eat it.

I threw it in on Sunday with my dry rock, live sand and 2 capfuls of microbacter7 each day.
Today is thursday, and its reading 8+ ppm ammonia and 5+ nitrites...

Is there such thing as too much ammonia or nitrites for a cycle? Or does it not matter and let it run its course and do a 100% water change once I am ready for fish by week 4-6?

I think you are okay. Just go slow and keep a eye on the nitrite's and nitrate's before adding fish. Once your nitrates are within range I would not recommend a 100% water change though. Maybe 10%. Make sure there is measurable ammonia before adding any thing. Patience is the key.
