Did your LFS
actually tell you what your results for NH3
were or just tell you it's safe to spend?
I would honestly recommend getting your own kits and testing these things for yourself. If there was never an ammonia or nitrite spike, your cycle hasn't even started yet unless there are signs of nitrate. Could you give a little more info in that regard?
