Maybe it's just me, but I havent had any real luck with biospira. I cycle my tanks the old fashioned way, with pure ammonia and waiting the few weeks if needed. There are no true shortcuts in saltwater.
I know youre dying to get some fish in there but just be patient. It will happen soon enough.
I would run the tank as normal and then either cycle it or do what you wanted to do. I would strongly suggest getting a test kit if you dont have one no matter what you decide on doing.
