Welcome to Canreef...not too often you see someone's first post being their build thread.

My advice on a nano is that you would probably be well served to look into replacing that hydrometer with a reflectometer. They come for a pretty reasonable price on e-bay these days and are a lot more accurate. Nano's don't have a lot of room for flexibility so where-ever you can reduce inaccuracy for not a lot of dough, you'll be well served.
