Just getting in this thread. Sounds like you leaped before you looked but have recovered extremely well!
The excel spreadsheet is exactly what I did. However, I did not spike my tank with shrimp or, heaven forbid, live fish to jump start the cycle. I used cured LR plus dry rock and a medium depth sand bed in mine. Mine "soft" cycled. In other words, I did not get a giant Ammonia spike. It only got up to around .25 ppm and dropped to 0 within 2 days. I was lucky. This does NOT happen very often from what I have been able to gather.
Maybe I missed it, but are you going to run a sump? I added a filter sock to mine to remove stuff I didn't like seeing. (After learning about Cyano!) It really isn't needed with a skimmer, But everyone does theirs a little differently.
I didn't see it mentioned, but do not do a water change while the tank is in cycle. The Cycle can take up to 8 weeks. Some times longer. Some times shorter. Test, test, test! Once you THINK the cycle is over, take a sample of your water to TWO LFS's and have them test it. IF either, or both, use test strips to tell you, never, ever step foot into that store again!
Good luck. I'm still new to this world. I have learned a LOT over the past year and still have the ability to remember the questions and issues that come from being a stone cold noob!
